Temperature measuring transducer for DIN rail and/or in the sensor head
●Simple measurement of temperature differences
●Self-built plug including
●large distance between the two sensors is possible (4-wire connection)
●Infinitely adjustably rotatable cable outlet for clean alignment
●Different characteristic curves are possible
Temperature difference measuring at two process locations, with
very low installation effort and compliant 4..20 mA 2-wire system.
The ETSD1 und ETSD2 sensors measure temperatures T1 and T2
at the respective process locations, each using a platinum
resistance sensor. In addition to the sensor, ETSD1 contains a
microcontroller circuit which calculates the difference between the
two temperatures (T1-T2), and outputs it via an amplifier as a
4..20 mA signal. Two outputs with different characteristic curves are
available as standard.
Altogether the circuit requires < 4 mA, and so it was possible to implement a 2-wire system (including wire break recognition).
