Please check out our newer model 2-wire transmitter TX13 Series (TC) and TX12 Series (RTD) with more advanced features at a lower price. The economical OMEGAâ„¢ TX91 and TX92 two-wire transmitters provide an output current of 4-20 mA proportional to the mV signal of a thermocouple or to a two- or three-wire RTD sensor input.The TX91 or TX92 is very compact and can mount directly within OMEGA’s NB1 cast iron protection head. By having the transmitter near the sensor, the effects of electrical noise can be minimized and long runs of thermocouple wire can be eliminated. Specifications Output Range: 4 to 20 mA DC Zero and Span Adjustment Range: ±25% Accuracy: ±0.1% FS (includes effects of linearity, hysteresis and repeatability) referenced to the mV input Ambient Temperature Range: -32 to 85°C (-25 to 185°F) Storage Temperature Range: -65 to 90°C (-85 to 19°F) Supply Voltage: 11 to 44 Vdc; 24 Vdc recommended Max Loop Resistance: (Vs - 11 V)/0.020A Dimensions: 29 H x 45 mm D (1.125 x 1.75") (height includes terminal strip) Weight: 50 g (1.5 oz) Examples of pricing for popular models is referenced in the "To Order" box.
