 Long
distance accuracy Temptran™ Temperature Transmitters amplify
the low-level signals from RTD's or thermocouples to an industry
standard 4 to 20 mA current signal proportional to temperature.
Unlike resistance or voltage, current signals are immune to resistance
in extension
wires and stray electrical noise. This lets you receive accurate
signals from a sensor located thousands of feet away. The 4 to
20 mA
output signal and DC power share the same wire pair. You don't
need to run power wires to every sensor location. RTD transmitters
also linearize the signal to temperature, making them excellent
low cost signal conditioners.
Engineered for Reliability
Over 175,000 Minco
transmitters are currently giving trouble-free service in installations
around the world. Two factors behind Temptran™
Temperature Transmitters
exceptional stability and longevity are:
· Minco encapsulates all electronics in epoxy to exclude
contaminants and protect
components.
· Standard fixed-range transmitters feature ±5%
adjustability using 20 turn trimpots.
Because a complete rotation of the trimpot represents only 0.25%
of the span, slight movements from mechanical shock cause only
negligible output change. In contrast, many competitive transmitters
have wide ranging zero and span. Some even use single-turn potentiometers.
With zero and span far more sensitive to potentiometer shifts,
a minor bump can void the transmitter's calibration.
Easy to Install
Compact Temptran™ Temperature
Transmitters
fit nearly anywhere. You can install most models in standard electrical
utility boxes and elbows. Or Minco offers a complete selection
of complementary connection heads. DIN rail mounting options are
also available for instrument cabinets.
Intrinsic Safety
Most Temptran™ Temperature
Transmitters
are rated intrinsically safe by Factory Mutual, a recognized testing
authority for safety in hazardous areas. Installations must include
a suitable barrier. A list of barriers FM approved under the system
concept for use with Temptrans can be found in our FM Documentation.
