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.
