Active temperature sensor:
- Supplied by external energy source
- Agile communication with the downstream control system
- Active reaction to changes in their environment
- Can be combined with other parameters such as humidity, Pressure, air quality, etc
- Active intervention in temperature control possible - thanks to smart room operating units
Passive temperature sensor:
- No external power supply required, encapsulated element
- The electrical resistance in the temperature sensors is measured by applying voltage
- Changes in resistance indicate changes in the ambient temperature (easy to read in the temperature-resistance table)
- Most favorable variant if no other parameters are to be read out
When is a temperature transmitter required?
Transmitters are required if temperatures are to be recorded from remote measuring points in order to compensate for cable lengths using standard signals (0-10V, 4-20mA, bus technologies such as Modbus or W-Modbus) and to generate standard signals.
