Application examples
1
Two sensors with measuring input (RTD or TC) in remote installation with the following advantages: drift
warning, sensor backup function
2
Integrated transmitter - 1 x RTD/TC or 2 x RTD/TC for redundancy
Endress+Hauser offers a comprehensive range of industrial thermometers with resistance
sensors or thermocouples.
When combined with the temperature transmitter, these components form a complete
measuring point for a wide range of applications in the industrial sector.
The temperature transmitter is a 2-wire device with two measuring inputs. The device not
only transfers converted signals from resistance thermometers and thermocouples, it also
transfers resistance and voltage signals using the PROFINET
via the 2-wire Ethernet connection according to IEEE 802.3cg 10BASE-T1L. The
transmitter can be installed as an intrinsically safe electrical apparatus in Zone 1
hazardous areas. The device can be used for instrumentation purposes in the terminal
head form B (flat face) according to DIN EN 50446.
Standard diagnostic functions
• Open circuit, short-circuit, corrosion of sensor cables
• Incorrect wiring
• Internal device errors
• Overrange/underrange detection
• Ambient temperature out-of-range detection
Corrosion detection as per NAMUR NE89
Corrosion of the sensor connection cables can cause incorrect measured value readings.
The transmitter offers the possibility of detecting any corrosion of thermocouples, mV
