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 protectcomponents.
- 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.
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.
