PRH-622 – Relative Humidity and Temperature Sensor - Duct Mount
Relative Humidity and Temperature Sensor - Duct Mount
Description
The new RH-600 range of humidity and temperature sensors offer the latest technology high precision and accuracy RH & T element, and installed in our new revised robust 600 series housing. The housing has an added benefit of being easy to install with the new hinged lid, which can also be screwed closed to make the unit tamperproof. An optional multi-line backlit LCD display is available, along with a direct PTC/NTC sensing element (when this option is required, the type of element must be specified at the time of ordering). Output signals of 0-10Vdc, 0-5Vdc or 4-20mA (loop or externally powered) for all measured values and RH are available as standard. A custom output range for temperature can be requested, between –20 and +50°C (–4 to +122°F). The -UN has a single output which automatically determines whether to run in current or voltage mode, no more jumpers or switches to worry about.
Features
-High stability and reliability
-Self-detecting output (-UN types)
-Snap-fit cover
-Fully configurable LCD display option
