Product overview
PCT400 Industrial Temperature Transmitter measures the
temperature of measured medium by using the feature that
the platinum resistance value varies with temperature and
shows a certain functional relationship. The transmitter
adopts the high-precision thermocouple and thermal
resistance as measurement elements, uses high stability
circuit for signal processing, realizes continuous
measurement of temperature, outputs industrial control
standard signal, and can have functions of display, remote
transmission etc.
The temperature measurement part of the product adopts all
stainless steel integration processing technology, and the
connecting box adopts 2088 aluminum housing. The product
has the features of strong shock resistance, quick thermal
response etc. The wire adopts special shielded cable, with
wide usage temperature range. It is easy to install, and
applicable to all kinds of automatic control systems for
temperature measurement.
