The OMEGA TX91 and TX92 miniature temperature transmitters are designed for use with thermocouples or RTD (Pt100) sensors, providing a 4 to 20 mA output that is proportional to the input signal. These compact transmitters can be mounted directly within the OMEGA NB1 cast iron protection head, which helps reduce electrical noise and eliminates the need for long thermocouple wire runs. The TX91 and TX92 feature an accuracy of ±0.1% full scale and include upscale break protection. They operate within an ambient temperature range of -32 to 85°C (-25 to 185°F) and have a storage temperature range of -65 to 90°C (-85 to 193°F). The supply voltage requirement is between 11 to 44 Vdc, with a recommended voltage of 24 Vdc. The dimensions are 29 mm in height and 45 mm in diameter, with a weight of 50 g. These transmitters are non-isolated and suitable for use with ungrounded probes.
The economical OMEGA 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.
