Temperature transmitter with digital display ST22

probe head-mountedPt100Pt1000

Temperature Transmitter with Local Display Output: 4-20mA. RS485 Accuracy: ±0.5%FS Introduction ST22 Temperature transmitter use PTIOO/PTIOOO temperature sensor as the sensing element, signal is amplified into standard signal such as 4-20mA, RS485 etc. There are linear correction circuit applied in the transmitter, make sure the entire transmitter has very good accuracy.
