MOORE 750E1B2GNNNF SST 750 Temperature Transmitter

The MOORE 750E1B2GNNNF is a high-accuracy temperature transmitter and signal isolator from the SST 750 series by Moore Industries. It converts input signals from thermocouples (J,K,S,R,B,E,T,N) or RTDs (Pt100, Cu50, Pt1000) into a standard isolated 4-20 mA or 0-10V DC output. The device is designed for reliable temperature monitoring in harsh industrial environments, featuring 3kV isolation, a wide operating temperature range, and IP65 protection. It is a key component in applications such as petrochemical reactors, power plant boilers, and metallurgical furnaces.

High Accuracy and 3-Way Isolation

The 750E1B2GNNNF achieves ±0.1°C accuracy for thermocouple inputs and ±0.05°C for RTD inputs over a wide temperature range (-200°C to +1800°C). It features built-in cold junction compensation for thermocouples and lead-wire resistance elimination for RTDs. The 3-way isolation (input, output, and power) provides 3000V AC isolation, effectively blocking common-mode and differential-mode interference from VFD harmonics and high-voltage cables, ensuring stable signal transmission.

Wide Environmental Tolerance

The transmitter operates reliably in ambient temperatures from -40°C to +85°C and can be stored from -55°C to +100°C, making it suitable for arctic outdoor installations and high-temperature industrial zones. The IP65 housing provides protection against dust, corrosion, and water splashes, ensuring long-term reliability in chemical and petrochemical environments. The ultra-slim 22.5mm DIN rail design allows high-density mounting in crowded control cabinets.

Application Domains

The MOORE 750E1B2GNNNF is used in petrochemical plant reactor temperature monitoring, power plant boiler tube temperature sensing, metallurgical furnace hot blast stove temperature acquisition, food and pharmaceutical processing thermal control, and HVAC chiller/boiler temperature monitoring.
