Overview
Enviro Test Construct high precision temperature is a high-performance field-mount temperature transmitter that accepts a single sensor input. This input can be from a RTD, thermocouple, ohm, or DC millivolt. It converts the sensor input to a 4 mA to 20 mA DC analog signal.
Features
- Dual-compartment field-mount housing
- TUV Nord SIL 2 or 3 Certified
- 20 Input Types
