18-812IS RTD Transmitter, FM Approved and Intrinsically Safe

RTD Input, 100 Ohm, Pt 0.00385 FM Approved, Intrinsically Safe Non-Isolated +/- 0.1% Full Scale Accuracy Factory Calibrated Mounts In Standard RTD Connector Head Fully RFI Protected 18-812IS series of  signal transmitters provide accurate and reproducible conversion of RTD signals to 2-wire 4/20 mA outputs. Their small size allows easy, space saving mounting in most standard RTD connection heads. This provides a compact mounting assembly located at the point of measurement. Operational errors due to noise pickup and leadwire resistance errors are virtually eliminated. This assures a stable 4/20 mA output signal transmitted directly from the measuring source. Each transmitter is supplied pre-calibrated to standard temperature or resistance ranges. Accessible multi-turn trimmer pots provide for a ±25% zero and span adjustment and allow for precise 0.1% F.S. calibration. RFI protection meeting SAMA PMC 33.1-1978- 2 abc requirements is achieved by unique input and output signal filtering
