 Explosion-Proof Room Sensor For Wall-Mounting
How do you safely sense ambient air temperature in a hazardous atmosphere? This problem has long puzzled contractors designing HVAC/R systems for paint booths, chemical storage rooms, explosives plants, and other installations where flammable materials may be present. Until now, the only solution has been a bulky, probe-style explosion-proof assembly which was designed for insertion into a pipe, not mounting on a wall.
Now Minco introduces a series of RTD's and thermistors packaged in a compact (3.7" x 2.0" x 1.6") explosion-proof enclosure that is UL-listed and CSA-approved for Class I, Groups C and D; Class II, Groups E, F, and G; and Class III areas. (Request Minco Application Aid #19 for an explanation of these classifications.)
The sensor features:
- Two 1/2-NPT threads, compatible with standard conduit fittings
- Copper-free aluminum construction
- 100 ohm or 1000 ohm platinum RTD sensing element
- 2252 or 10,000 ohm thermistor sensing element
4 to 20 mA transmitters (FM-approved) are optional, but must be mounted in a separate enclosure.
