The Model RTT80 is a microprocessor-based temperature transmitter with FOUNDATION™ Fieldbus Communication Protocol. It receives input signals from thermocouples, RTDs, resistance (ohm), or voltage (mV) sources.
FEATURESSuperior accuracy and long term stability from microprocessor-based technology.One unit configurable for a variety of Thermocouple (TC) and Resistance Temperature Detector (RTD) inputs.Supports 2-, 3-, or 4-wire RTDs.Allows average or difference measurement.Automatic sensor backup – a second sensor starts measuring temperature if the primary sensor is not functioning correctly.Temperature-dependent switching between sensors which are used in different measuring ranges.FOUNDATION™ Fieldbus H1, 31.25 kBits/s.Fieldbus Foundation Interoperability tested (complies with ITK 6.1.0) and registered with the Fieldbus Foundation.Link Master capable.Features multiple function blocks to support control in the field.Drift alert or alarm if the deviation between sensor 1 and sensor 2 is less than or greater than a predefined limit value.Sensor corrosion detection.Thermocouple cold junction compensation.Galvanic isolation 2 kV input to output.Rich on-board diagnostics.Optional digital indicator.Available as a basic module that can mount to a surface or DIN rail, or in explosion-proof universal or dual compartment housings for remote mounting, and integral sensor and thermowell mounting.
