ATM/IS Series 83 precision pressure transmitters from STS Sensors, Danbury, CT, have intrinsically safe approvals, such as FM and CSA Class I Div. I and ATEX EEx 1G ia IIC T3-T6 certifications. The modular sensors have 316L SS construction, offer a range of pressure and electrical fittings, and are available with F.S. ranges from 1 through 10,000 psi. Proof pressure is typically greater than 3 times F.S.; static accuracy is 0.1% typical. The 10–30 VDC supply voltage provides a 2-wire current loop 4–20 mA output for the F.S. range.
