Sensors

Contel supplies every type of sensor required for the control of air-conditioning systems, mostly from the SIEMENS SYMARO Series.

• Temperature sensors: air and water.
• Pressure and differential pressure sensors: air, water and refrigerant.
• Relative and absolute humidity.
• Enthalpy: for energy savings (utilizing the energy of the outdoor air).
• Flow rate:  water and air.
• Air quality (VOC and CO₂).
• Human presence in the room.
• Energy consumption of cold and hot water (measuring the flow rate and the difference in temperatures).
• Gas concentrations in the air, mainly in car parks and swimming pools (CO, CO₂, LPG and chlorine).
