Sensor (HVAC)

Sensor (HVAC)

Sensors for HVAC applications are precision measurement devices designed to monitor and control environmental parameters such as temperature, humidity, pressure, and air quality. These sensors typically feature analog outputs (0-10V or 4-20mA) or digital communication protocols like Modbus RTU, BACnet MS/TP, or KNX. Common types include duct temperature sensors with Pt1000 or NTC thermistor elements, differential pressure transmitters for filter monitoring, and CO2 sensors for demand-controlled ventilation. The sensing elements are housed in robust enclosures with IP54 to IP65 protection ratings, suitable for installation in air handling units, ductwork, or room environments.

These sensors are deployed across commercial buildings, industrial facilities, and residential complexes for HVAC automation. Typical applications include variable air volume (VAV) box control, chiller plant optimization, boiler management, and cleanroom environmental monitoring. They integrate seamlessly with building management systems (BMS), programmable logic controllers (PLCs), and direct digital control (DDC) panels. Key sectors include data centers requiring precise temperature and humidity control, pharmaceutical facilities needing pressure cascade monitoring, and office buildings implementing energy-efficient demand-controlled ventilation.

Our HVAC sensor category includes duct temperature sensors (e.g., model series TSD-100 with Pt1000 elements), room temperature sensors (e.g., RTS-200 with selectable output ranges), differential pressure transmitters (e.g., DPT-300 with 0-10V output and 0-500 Pa range), and humidity transmitters (e.g., HMT-400 with capacitive sensing elements). The article codes follow a structured format: first two letters indicate sensor type (TS for temperature, DP for differential pressure, HM for humidity), followed by a dash and a three-digit model number, then optional suffix for output type (e.g., -A for analog, -M for Modbus).
