Field Mounted Temperature Transmitters Introduction

Field-mount temperature transmitters are designed with a dual compartment housing that keeps moisture, humidity, or other contaminants from getting into the transmitter's electronics.

This particular kind of temperature transmitter comes installed in its own exterior housing, which enables it to be used “in the field” where conditions may call for extra protection, such as in high-performance industrial operations. Field mounted transmitters can be located relatively close to the sensor to increase the strength of the signal.
