Description.
The LPN-H is a complete relative humidity and temperature sensing module, with two independant loop powered
4~20mA output signals, representing 0~100%RH and 0~100C.
Two versions are available:
(i) Wall mount.
(ii) Duct mount.
Both version come complete in an industry standard aluminium connection head. The relative humidity sensor and
temperature compensating sensor protrude from the head inside a protective cap. This cap allows air to circulate to the
sensors.
Reliability.
The wide operating 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.
