4 - 20 Ma - 3 Wire Industry Standard Transmitters - Material: Aluminium

Often it is more cost effective to replace a sensing head with one which is pre-calibrated at a testing station, thus reducing disruption of the measuring system. Technovation offers such an industry standard 4-20mA transmitter consisting of a gas sensor, its associated circuitry with a display and in a weather-proof housing.
FEATURES
The three-wire transmitter allows the power and signal to be realized on a three-core wire. One core for positive supply of 12 to 24 VDC, the second core for the 4 to 20 mA output and the third core for the 0 volt supply. The transmitter is immune to voltage drops from long runs and noise from motors, relays, actuators, switches, transformers and industrial equipment.
APPLICATIONS
Every transmitter is supplied pre-calibrated for a customer specific range. The table below gives an indication of t he gases/ranges offered. These transmitters can be connected to a DC system which supplies the DC Power for the module. They could also be connected to stand alone controllers and PLCs and other data acquisition systems
