Confidence is good, measuring is better! Proven and innovative measuring technology for compressed air

For years CS Instruments GmbH has been one of the worldwide leading manufacturers of measuring technology for the compressed air. Long-term experience in production, supply and drying of compressed air is contributed to the research, the development and the production of portable and stationary measuring instruments.


  • DP 500 - Portable dew point meter for compressed air and gases

    The dew point meter DP 500 with data logger is the ideal portable service instrument for dew point measurement for all types of dryers down to -80°Ctd dew point. The 3.5“ graphic display with touch screen makes the operation very easy. The graphic indication of coloured measuring curves is unique. Ideal for measurement of the current dew point and for graphic indication of the dew point curve/ the switching behavior of the dryer over a longer period of time.

  • Flow sensor for heavy duty industrial applications

    The new flow sensors VA 550/ 570 work according to the calorimetric measuring principle. Therefore an additional temperature and pressure compensation is not necessary.
    Due to its robust design, the aluminum die cast housing, the robust sensor tip made from stainless steel 1,4571, the new VA 550/ 570 are suitable for demanding industrial applications. An ATEX version is available for applications in explosive areas. For flow measurement e. g. of natural gas there is a version with a DVGW admission.
    Contrary to the previously used bridge circuit the newly developed evaluation electronics records all measured values digitally. This allows very precise and fast measurements with a wide temperature range of up to 180 °C. The measuring span is 1...1000 and enables therefore measurements in very low as well as in very high flow speeds of up to 224 m/s.
    VA 550/ 570 has an integrated Modbus output as a standard with which all parameters like Nm³/h, Nm³, Nm/s, Nl/min, Nl/s, kg/h,
    kg/min, ft/min, °C etc. can be transferred. All parameters can be adjusted directly at the instrument (via display) or via the PI 500 hand-held measuring instrument resp. the Service Software. Of course there are also 2 x 4...20 mA analogue outputs available for flow and temperature and a galvanically isolated pulse output for the total consumption.
    A remote diagnosis can be carried out via Modbus and all relevant parameters can be checked and changed if necessary. So it is possible to change e. g. the gas type, the inner diameter, the scaling and so on or the zero point resp. the leak flow volume suppression in case of changed process conditions.
    Via remote diagnosis and status update e. g. temperature exceedings, failures of the sensor or the calibration date can be determined.

  • Leak detector - LD 400

    Highly sensitive leak detector

    The leak detector LD 400 is a handy device for detecting often hidden perforations in pipes and tubes. It is the further development of the proven LD 300 and impresses through a significantly more sensitive sensor technology to provide improved support during the leak detecting process.
    The functional principle is ingeniously simple

    Leaking gas causes ultrasonic noise. However, a leak must have the size of approximately 1 mm and the pressure must have reached approximately 7 bar before the frequency emits a sound that is audible to the human ear. The leak detector LD 400 can locate leaks in the ultrasonic range, even from a distance of several meters. The LD 400 translates the ultrasonic sound into an audible frequency and makes it easier to detect even the finest holes in the pipes. Sound-proof headphones ensure that the technician can hear the acoustic signal even in the noisy environment of an industrial plant.
    Complete discovery of leaks

    Additionally, in extremely loud rooms, we recommend the use of a shotgun microphone with a directional tip. It functions like a directional microphone, prevents annoying background noises and also facilitates the precise localization of leaks in inaccessible areas.
    Additionally, an ultrasonic transmitter whose signal penetrates through the smallest openings can be used to detect leaks in pressureless systems.
    Saving energy and money with high-tech

    In Germany alone, 60,000 compressed air systems are using 14 million MWh of electricity each year. “15 to 20 percent of it can be easily saved,” says Peter Radgen of the Fraunhofer Institute in Karlsruhe,
    “because a large part of the energy that is used by the systems to generate and constantly maintain air pressure escapes through leaks in the pipes.” In other words: a hole with a diameter of one millimeter results in energy costs of approximately EUR 270 per year. Depending on the size of the facility, the energy saving potential can amount to five- or even six-figure sums.

    This representative example demonstrates vividly that the acquisition of the leak detector LD 400 is already profitable with only four leaks. Furthermore, the size of the leak grows through steady pressure of the escaping gas. The permanent burden of energy costs grows too, and thus, the leak detector LD 400 prevents additional cost explosions.

    Energy analysis – consumption measurement – leakage calculation at compressed air systems

    If we talk about operational costs of compressed air plants we are actually talking about the energy costs as they make up about 70 to 80 % of the total costs of a compressed air plant.

    Depending on the size of the plant this means considerable operating costs. Even in smaller plants this may quickly add up to 10,000 to 20,000 € per year. This is an amount which can be considerably reduced – even in the case of well operated and maintained plants.

    Does this also apply to your compressed air plant? Which actual costs per generated m³ air do you actually have? Which energy is gained due to the waste heat recovery? What is the total performance balance of your plant? How high are the differencial pressures of single filters, how high is the humidity (pressure dew point), how much compressed air is used? …

    By means of the new multifunction measuring instrument DS 500 mobile and the suitable sensors and meters all these questions can be answered easily. For example by means of a long-term measurement over 7 days, data recording and evaluation at the PC.

    By means of the multifunction measuring instrument DS 500 mobile for the first time all measuring data of a compressor station can be recorded, indicated and evaluated.

    At 12 freely assignable sensor inputs all CS Instruments sensors can be connected as well as any optional third-party sensors and meters with the following signal outputs:

  • Residual oil measurement OIL-Check

    The residual oil OIL-check sensor measures the vapor content of residual oil in compressed air. By means of sampling a representative partial volume flow is removed from the compressed air and supplied to the OIL-check. Due to the continuous measurement limit violations are immediately identified and corrective actions taken.

Product news

  • Differential pressure sensor for testing filter performance

    The small and easy-to-install differential pressure sensor allows you to test the filter performance of the compressed air system by measuring the differential pressure across the filter element (an indication of how much the filter element is soiled). Thus it helps to maintain the required compressed air quality permanently. The sensor has a compact design with mounting bracket and sensor socket combined in one piece.

  • Mobile Dew Point and Pressure Measurement - DP 400 mobile

    For measurement of all humidity parameters under pressure up to 16 bar.
    The portable dew point meter with integrated, rechargeable battery has been developed especially for the eld use. Besides a highly precise dew point sensor the device also contains a precise pressure sensor up to 16 bar. So in addition to the dew point in °Ctd, the temperature in °C and the line pressure in bar also further moisture parameters (% RH, mg/m3, g/m3) as well as pressure-dependent measuring values (g/kg, ppm v/v, atm. dew point °C) can be calculated.
