GENERAL
This programmable 2-wire Pt100
transmitter is designed for mounting
inside the standard connecting head of a
temperature sensor. It is the
continuation of the UNIFLEX T/TEX
series and fulfils all the requirements
regarding flexibility, reduced stocks and
safety against electromagnetic effects.
By means of a PC and the standard
programming set, adjustment for the
required measuring range and
parameters is performed.
DESCRIPTION
The transmitter has an input for a Pt100
sensor.
Measurement is possible in 2-, 3- and
4-wire connection
