US Gauge’s IDT intrinsically safe pressure transmitters are specially designed for use in hazardous area pressure measurement applications that demand a compact design, like chemical & petrochemical manufacturing, control, skids, and Christmas trees for the oil and gas industry. This Intrinsically safe pressure sensor includes approvals FM US and FM Canada, ATEX, and IECEx for worldwide users’ pressure measurement requirements.
The IDT provides superior performance and versatility in a compact design, for use in a variety of applications including upstream oil and gas, general industrial end users, skid builders, and OEM’s. The IDT offers precision accuracy at +/- 0.2% FS (BFSL) typical. The design incorporated a stainless steel isolation diaphragm (option Monel or Hastelloy) and 316 stainless steel housing for use with most media types.
The IDT pressure ranges go from a full vacuum to 5000 psig, or vacuum to 340 BAR, in absolute, compound, gauge, or vacuum pressure types. This transmitter accepts both regulated and unregulated excitation voltages and provides output signals in 4-20 ma, 0-5 VDC, 1-5 VDC, 1-6 VDC or 0.5 to 4.5 VDC. The IDT pressure sensor is manufactured in the USA.
