First for ATEX-approved humidity
transmitters
A new range of ATEX approved intrinsically safe relative humidity transmitters are believed to be the only products of their type on the market.
Instrumentation specialist Lee-Dickens has released its first range of ATEX approved intrinsically safe relative humidity transmitters, believed to be the only products of their type on the market The HP140IS and HP150IS are duct- and wall-mounting relative humidity transmitters aimed at potentially hazardous or explosive applications in industries such as gas, petrochemical or bulk solids

The new Beta signal conditioning modules build on the field experience of Alpha, which has been manufactured since 1985 and now includes over 30 basic models and thousands of variants
Both products are approved to EEx iia IIC T4 at 70C ambient for use in Zone 0 conditions.
The probes, which use a capacitive sensor, operate as two-wire transmitters and produce a 4-20mA output proportional to 0-100% relative humidity, with accuracy of better than +/-2.0% for 0-95% relative humidity.
The sensor is suitable for use in operating temperatures from -10 to +100øC and the electronics from -10 to +70C.
The HP140IS probe and flange are constructed of stainless steel and come fitted as standard with a sintered bronze guard.
The HP150IS has a plastic cage as standard and each probe comes with mating connector.
Power supply voltage and interface from the safe area to the transmitter is via approved barriers available from Lee-Dickens. Request a free brochure from Lee-Dickens ...
