Pt100 temperature sensor 101PT(A19G)

resistanceanalogreference

In order to measure both pressure and temperature of pressure medium simultaneously at the same point, model 101PT(a19G) Pressure & Temperature Sensor (PTS) is developed from a pressure sensor. This PTS is manufactured as either an analogue PTS or a digital PTS, depending on either a temperature sensor or a digital ASIC integrated in it. It covers a wide measuring range of pressures from 0.1bar to 1000bar, with pressure reference of gauge (relative), absolute, or sealed gauge. In meanwhile, it can measure the medium temperatures in its operating range either from -40°C to +125°C when it is the analogue PTS or from -40°C to +85°C if it is the digital PTS. When it is manufactured as the analogue PTS, its pressure output is mV/V signal resulting from a Wheatstone bridge circuit while its temperature output from the integrated temperature sensor is either resistance change in Ohms of a Pt100, or mV signal of a thermal diode. This output signal from the temperature sensor can be used not only for sensing medium’s temperatures but also for additional temperature compensation for the pressure signals by Buyer. When it is manufactured as the digital PTS, its pressure and temperature outputs are all digital signals of either I2C or SPI, resulting from the digital ASIC. One of the most common application of this PTS is to integrate it into a customer-tailored housing to form a customized PTS, in order to facilitate measurements of both pressure and temperature of the pressure medium simultaneously at the same point.
