LS Control is a 100% Danish company, which since 1969 has delivered electronics for controllers and regulators to quality conscious companies. Initially our strong point was electronic components for ventilation plants, and even though this is still an important business area, many other areas and products have been included since.
Our comprehensive experience and on-going training programs are very important to our customers. Furthermore we work according to ISO 9001 standards, resulting in a tight and structured project management leading to uniform and high quality products.
Equally important, we are not only an R&D company, we also implement the projects including manufacturing of prototypes, 0-series and final products. We undertake the entire process thereby minimizing the number of partners the customer needs to involve in the project. Depending on the project the production will be in Denmark or abroad.
The same strong and broad foundation characterizes the owner structure. The company is owned by four persons and together they provide security and continuity; Per Nielsen, Managing Director; Stig Petersen, Sales and Marketing; Martin Jensen, Research and Development; and Jens-Erik Hegelund, IT and Quality Assurance.

The CO₂sensor is a combined sensor and regulator for a wide range of applications. For full control of ventilation in offices and/or as CO₂sensor in more complicated ventilation systems.
It is provided with two independent 0-10V outputs. A proportional output based on the current CO₂level, and one control output designed for control of damper or ventilation plant. Room temperature can be included as a control parameter.
Both design and ease-of-use have been prioritised:
•Easy to set-up, install and adjust.
•Maintenance free.
•Discreet sensor ideal for mounting in households and office
environments.
•Control of ventilation plant based on temperature and CO
level.
•Possible to adjust on the basis of CO₂level alone.
•Possible to use as CO₂meter and ventilation controller
simultaneously.
•PID (proportional-integral-derivative) adjustment
•Two output control signal ranges available: 0-10V or 2-10V.
CO₂sensor is also available with integrated MODBUS communication protocol for retrieval of data from the unit. In addition the CO₂sensor is availbale for duct mounting with or without MODBUS protocol.
The CO₂ sensor is a sensor for a wide range of applications. In combination with eg. MultiController it could be used for full control of ventilation in a single room and/or as CO₂ sensor in more complicated ventilation systems.
The CO₂ sensor is provided with a 0-10V proportional output based on the current CO₂ level to be used as input signal for the controller of a damper or ventilation plant.
Both design and ease-of-use have been prioritised.
In combination with our 24V DC power supply type PowerSupply 0.1-24E with integrated setpoint relay a very easy implemented on/off operation is achived. For more fine tuned regulation LS Control recommend using the MultiController E Regulate or MultiController E 0-100%.
PowerSupply 0.1-24 E is a 24V DC power supply for 230V AC mains supply through a SMPS power supply.
The power supply is intended for use with e.g. the ES 899 CO2 sensor, but it is also suitable for use with other products.
Furthermore the unit is able to compare the voltage on a 0-10V input with the potentiometer setting on the printed circuit board. If the input voltage exceeds the potentiometer setting the relay opens. It is also possible to connect an external potentiometer or a 0-10V signal instead of the internal potentiometer.
Power supply with jumper controlled output voltages; 16.5 VDC or 24 VDC. Light indicator for power on output. The output voltage is galvanic separated from the input voltage (double insulation).
Sensor for measuring of temperature in ventilation ducts.
The sensor measures the temperature of the air in the duct by a NTC sensor. It is mounted with bracket (to be ordered separately) which can be used as a drilling template. After the holes have been drilled in the duct (18 and 5 mm drills), the bracket and sensor is mounted with screws.
Sensor for measuring of temperature and humidity in ventilation ducts.
The sensor measures the temperature of the air in the duct by a NTC sensor and humidity by a humidity sensor. The sensor is mounting with a bracket which can be used as a drilling template (to be ordered separately). After the holes have been drilled in the duct (18 and 5 mm drills) the bracket and sensor is mounted with screws.
The sensor must be turned in such a way that the humidity sensor faces downwards (and the NTC sensor consequently faces upwards) - thereby ensuring that condensate, if any, does not rest on the humidity sensor but runs out of the sensor.
Sensor for measuring of air velocity in ventilation ducts.
The sensor uses the cooling properties of the air to measure the air velocity in ventilation ducts. It comes with a mounting bracket which can be used as a drilling template. After a hole has been drilled in the duct (18 and5 mm drills) the bracket and sensor is mounted with screws.
It is important that the sensor is not installed in an area with turbulens, i.e. it should not be installed in proximity to an elbow or a junction.
Pressure transducer 0-10kPa for measuring of negative, positive or differential pressure. The transducer measures negative, positive or differential pressure depending on the connection of the tube. As standard supplied for measuring of negative pressure.
The pressure transducer is designed for operation with equipment with a power supply of 15-24V DC. The pressure transducer is specially developed for operation on ventilation plants. It may, however, also be used for other purposes.
The pressure transducer supplies a 0-10V output control signal.
The pressure transducer is intended for use in clean, dry and non aggressive air/gas.
PressureTransducer 0-25Pa with 0-10V DC output signal based on micro-flow measurement.
The pressure transducer is equipped with a half/full scale selector. Use the jumper to switch between half scale and full scale. In half scale mode, the output voltage is 10 volt at 50% of the sensors maximum. Example: In half scale mode the pressure transducer has an output of 0V at 0Pa and 10V at 250Pa. If the unit in half scale mode is exposed to a pressure outside the max range, the output voltage may increase to 12V.
The pressure transducer is available for other pressure ranges than the one mentioned above.
NB! The pressure transducer is only to be used in a non condensing environment and in non aggressive air.
PressureSensor - sensor for measuring of negative, positive and differential pressures. The output voltage is standard 0-10V, and it is proportional to the surrounding pressure. The pressure sensor is specially designed for use in ventilation plants, but it can also be used for other purposes.
Pressure alarm with internal pressure switch, change over relay and battery backup of 6 - 8 hours in case of power failure.
The pressure alarm is intended for control of ventilation plants, but can also be used for e.g. control of local exhaust ventilation.
If the pressure drops, an integrated audible and red light alarm is activated. The light alarm will be deactivated when the pressure returns to normal level. It is possible to mute the audible alarm by pressing the button on the front, and it will not revert to active mode until the pressure has returned to normal level. A green light on the front is active when power is connected.
For proper functioning of the pressure alarm, power must be connected to clamp L2 from the switch operating the ventilation plant. Clamp L1 must be connected to mains supply which only is disrupted in case of power failure.
When the ventilation plant - and at the same time also the pressure alarm - is turned on - the red light alarm will be activated (low pressure) there as the audible alarm will only be activated if normal pressure is not reached after approx. 30 seconds.
