The LPN-H is a complete relative humidity and temperature sensing module, with two loop powered 4~20mA output signals, representing 0~100%RH and 0~100ºC.
Two versions are available:
(i) Wall mount.
(ii) Duct mount.
Both versions come complete in an industry standard aluminium connection head.
The digital relative humidity sensor and temperature compensating sensor protrude from the head inside a protective cap. This cap allows air to circulate to the sensors.
|LPN-H-W (rev 1)||Wall Mount, 0~100%RH Transmitter, 0~100ºC Transmitter.|
|LPN-H-D (rev 1)||220mm Duct Mount, 0~100%RH Transmitter, 0~100ºC Transmitter.|
|LPN-H-F||100mm Flange for LPN-H-D.|
Note: 0~200ºF temperature output optional. Please specify when ordering.
The wide range of the humidity and temperature sensors offer long term reliability over a broad range of applications. The sensors resist contaminating vapours such as organic solvents, chlorine, and ammonia.
The LPN-H-Ref system is designed to allow in situ calibration of LPN-H-W and LPN-H-D humidity transmitters. The LPN-H-Ref system consists of corrosion resistant stainless steel canisters containing humidity regulating salt solutions that replace the black protective filter on the sensor.
It is essential that the humidity sensor is mounted vertically with the filter at the bottom to prevent spillage.
