Bringing advanced technology to sensors

HVAC & Refrigeration

Designers and engineers in the Heating Ventilating and Air Conditioning (HVAC) industry sector, including those working on refrigeration systems, are constantly innovating to increase the efficiency and reduce power consumption of their equipment. This has led to advances in refrigerant fluid (R410A, R32, R1234yf, R717 ammonia…), refrigerant flow control, the use of variable speed compressors and blowers and electronic expansion valves. But pressure sensors play a key role in this quest of efficiency. With decades of experience and expertise designing pressure sensors for the HVAC/R business, Senzors supplies robust and reliable pressure transducers and transmitters at a competitive price. We have a wide variety of ranges (including compound ranges), housings, pressure ports, electrical connections, output signals. Most of our constructions are made of a single piece of 316L stainless steel and have no internal seals or gaskets. Our products’ design is adapted to the tough environments encountered in this application with adequate protection against EMI (electrical noise), large temperature variations, high humidity and vibrations.


  • Monitoring of refrigerant pressure in compressor-based chillers
  • Regulation and optimization of compressor speed
  • Control of refrigerant charge and discharge
