Multi Channel Scanner

A Temperature Scanner is a device that measures more than one temperature points or multi-channel. It is actually a multi-channel indicator that measures and displays signals of each channel one-by-one up to last channel and then returns to first channel and continues the process cyclically. This continuous cyclic process of measurement is called scanning. Temperature is most widely measured parameter in industry. By using a temperature scanner, temperature of multiple points can be measured in a single unit thus saving cost and space. Thus Temperature scanners are also called as multi-point indicators / scanners. Temperature Scanners are essentially based on digital technology or microprocessor/ microcontroller based. It is capable of measuring temperature from resistance temperature sensors like RTD Pt100 or from different types of thermocouples like J, K, R, S, T, B, E and N.

Now-a-days Temperature scanners are also capable of measuring other signals like 4-20mA, 0 to 1VDC, 0 to 5VDC etc from different transmitters. So we can call this device as Process Scanner as it not only measures temperature but also many other process parameters like flow, pressure, humidity, level etc.

Temperature Scanners have facility of alarm/ control relay outputs, serial communication port to connect to SCADA / DCS / PLC. Applications of Temperature Scanners are seen in almost all types of Industries.
