More About this Item

Transmitters are powered by 24 VDC and have an output of 4 to 20 mA. The capacitive sensor is accurate, rugged, and offers long-term stability with temperature resistance. The IP65 rated housing protects the unit from dust, sprays, and electromagnetic interference. A unique rotating body allows optimal positioning, while the three-button keypad makes setup and adjustments fast and easy. These units can be programmed directly via a computer. The process connection is G 1/2" stainless steel screw-in thread or 1/2" NPT that easily threads into existing sample ports. Select from two styles of transmitters with or without a display — for your demanding applications. Models with a display are more commonly used for monitoring at the application level, and features Min/Max, selectable display °F/°C display, Ftd or Ctd (temperature dew point), Atd (atmospheric dew point °F or °C), %RH, ppm, and mg/m3. Models without a display unit are ideal for OEM applications where monitoring is done in a process setting.
The optional quick-connect measuring chamber 37463-52 has a standard G 1/2 connection and ensures the transmitter has the optimal flow past the sensor. Use the optional two-output signal switch 37463-54 to add alarm capability when the selected limit value is exceeded.
