Model IDT - For Hazardous Area Applications

*** Call, email or live chat today with any questions or to place a custom order! ***

The Model IDT intrinsically safe pressure transmitters are specifically designed for use in hazardous area pressure measurement applications that require a compact design.

Intrinsically safe approvals for the IDT includes FM US and FM Canada (cFMus), ATEX and IECEx for worldwide users’ pressure measurement requirements. The IDT offers premium performance and versatility of use for many applications including upstream oil and gas, general industrial end users, and OEMs.

The IDT offers precision accuracy at +/-0.2% FS (BFSL) typical. The design incorporates a stainless steel isolation diaphragm and 316 stainless steel construction for use with most media types.

The IDT is offered in pressure ranges from full vacuum to 5000 psig and 15 psia through 300 psia. The transducer also accepts both regulated and unregulated excitation voltages and provides output signals such as 1-5 VDC, 1-6 VDC, 0-5 VDC, 0.5 to 4.5VDC and 4-20 mA.

The IDT transducer is manufactured in the United States under ISO 9001:2008 and meets ARRA.
