2 WIRE / 4 WIRE TEMPERATURE TRANSMITTER - 401

GENERAL DESCRIPTION
Analogik 2 Wire 4W temp, transmitters accepts Pt -100 input & thermocouples & gives 4 to 20mA output proportional and linear to input signal. Direct sensor connections are eliminated, due to which long run cable for pt -100 & T/C are avoided gives economical solution. The rack mounted, G - rail, field mounting as well as pipe mounting versions are available. The flame proof version with CMRS certification for II A, B, C & E are available.
In the head mounted 2W temp transmitter the sensor is attached at the bottom.
FEATURES
Three wire lead resistance compensation & built - in cold junction compensation
High accuracy typically 0.2% of F.S.
Drift free performance.
Rack mounted,field mounted,Head mounted, 2" pipe mounted, G rail versions available.
On - line calibration in case of flame proof version.
CONSTRUCTION & OPERATION
The glass epoxy, green masked, high quality components soldered PCB provides the drift free & reliable performance Low level signal mV from T/C & resistance of RTD are converted into voltage & fed to V to I converter. This further converts the signal into 4 to 20mA DC signal proportional to input. The highly stable current source & accurate reference is used to give good results. Up Scale or Down scale facilities are provided for sensor break protection.
APPLICATIONS
To avoid the signal loss & to avoid the expensive cables of the sensors the 2W - 4W transmitters is the best solution.
This is used as an isolation between field operations & central room is large, the Analogik 2W - 4W transmitters is the best, economical solution.
