Product Details
Industrial 4-20ma Hart Head Mounted Temperature Transmitter
Description
WNK temperature transmitter is installed into the top of the temperature transmitter. One side connected to the temperature probe and the other side
connected to the circuitry. Compact and inexpensive one is
available any time.
It specially designs for PT100. It inputs various RTD signal and
converts this signal into 4-20mA standard current signal after
linear processing. It has configurable measuring ranges and large
ambient temperature range.
Benefits
Measures temperature with a linear output signal
High accuracy across entire ambient temperature range
Reduces plant noise
Slim design, ideal for upgrade of installed PT100 probes with a
4-..20mA signal
Rugged design, fully potted electronic
