The FS300-100 Combi-sensor measures water pressure and inflow temperature in boiler systems. The sensor's analog pressure and temperature output allows system fine-tuning in conjunction with electronic control, which is extremely important in obtaining peak system efficiency, especially as emission level standards become tighter, says the company. The Combi-sensor incorporates an application-specific integrated circuit-controlled pressure-sensing element. The device has a pressure range of 0 to 3 bar relative, an overpressure of 6 bar, and a burst pressure of 10 bar. The operating temperature is 41 degrees to 230 degrees F (5 degrees to 110 degrees C). The unit has several optional features, including a press-fit or screw-in interface, alternative negative temperature coefficient characteristic curves or tolerances, and alternative pressure characteristic curves.
