Orange Research EXPLOSION-PROOF DP Piston or Diaphragm Sensors with Explosion-Proof Enclosures for Switches, Relays or Transmitters

Piston or Diaphragm Sensors with Explosion-Proof Enclosures for Switches, Relays or Transmitters
EXPLOSION-PROOF DP

Our Class 1, Div. 2 enclosures found throughout this catalog are popular for hazardous environments where explosive gases or vapors may be present. Our Class 1, Div. 1 Explosion-proof line, expands on that protection. The heavy-duty enclosures are designed to seal the electronics from environments where flammable gases or vapors often exist and to contain any potential explosions.

This explosion-proof line incorporates the same piston or diaphragm sensors and pressure bodies found in the preceding pages. We add an additional extension pin with a secondary magnet to trigger our reed switches or to control transmitter output. The secondary magnet and electronics are located in a sealed explosion-proof box adjacent to the pressure body.

The switches and electrical connections are housed in special UL, CSA, FM and ATEX approved enclosures. The cast aluminum housings have two mounting lugs, two 3/4” NPT electrical conduit ports, and meet the following specifications: Class 1, Gr. B, C, & D; Class 2, Gr. E, F, & G; and Class 3. They also meet NEMA 3, 4X, 7, 9, & 12 specifications.

Select from a variety of options such as follower pointers, red arcs and mounting brackets along with switch, relay or transmitter outputs.

• Class 1, Div. 1 rated enclosures
• Rugged, weatherpoof design
• Gauge, switch and transmitter versions
