  • Sintered stainless protective filter
  • Box with IP65 protection

Description

The COMECO RHV probe has the same features as the RHV model, but has an RS485 output/interface and is designed specifically for multi-point measurement and data acquisition in a network of up to 32 devices. Through a thin-film capacitive sensor and a platinum thermo-resistance, this probe measures the relative humidity and temperature of air and non-aggressive gases at atmospheric pressure and converts both parameters into information via a standard RS485 interface via ACSII protocol. The RHW is equipped with a convenient plastic box with IP65 degree of protection and two PG7 cable entries for convenient and fast network construction. This model can be additionally equipped with a stainless sintered filter to protect the sensor. Thanks to its reliable construction, network communication capabilities and low cost, the RHW probe is widely used in air conditioning, building automation and control in warehouses and other industrial premises.

RHW Sensor Applications:

RHW is widely used in various industrial and commercial sectors, including:​

  • Building Automation Systems: Monitoring and controlling climate conditions in office buildings, shopping malls and other facilities.​
  • Warehouses and logistics centers: Maintaining optimal conditions for storing goods by accurately measuring humidity and temperature.​
  • Manufacturing plants: Controlling the microclimate in production areas where humidity and temperature are critical for product quality.​
  • HVAC (Heating, Ventilation and Air Conditioning) Systems: Integration into HVAC systems to improve energy efficiency and comfort.​

Thanks to its reliable design and communication capabilities, RHW is ideal for applications requiring accurate and stable real-time humidity and temperature measurement.
