OMEGA (Stamford, CT) has developed the PRTXB and PRTXAL series 2-wire transmitters, which provide 4 to 20 mA signals representing temperature. The transmitter has a 316 stainless steel RTD Probe that captures minimum and maximum readings. According to the company, all battery-powered units have selectable units and an auto-shutoff time feature, and others have alarm outputs. They are ideal for food processing, HVAC, pressure vessels, or any temperature monitoring application.
