XR440 Thermocouple/Millivolt Modules

Quick Overview

Mvt modules enable the XR440 Data Loggers to accept a millivolt or thermocouple input on channel 3. The Mvt-20u, Mvt-100u, Mvt-107b and Mvt-500u are used solely for mV inputs but three modules (Mvt-11b, Mvt-22b, Mvt-50u) can be used for mV or thermocouple inputs (Type J, K, N, R, S, T, B, C, or E). A built-in precision thermistor on channel 1 provides ambient temperature readings and thermocouple cold junction compensation. An Mvt module configures the XR440 as follows: Ambient temperature on channel 1. Millivolt (or thermocouple) signal on channel 3. Channels 2 and 4 are 'Standard' channels and will accept Pace sensors, 0-5vDC or resistive signals.

Details

The MVT modules will configure the XR440 Pocket Logger as follows:

Channel 1: Ambient Temperature.*
Channel 3: MilliVolt or Thermocouple Input.
Channels 2 and 4: ‘Standard’ channels, suitable for any Pace sensors, 0-5vDC or resistive inputs.

*A built-in, precision thermistor provides ambient temperature readings and cold junction compensation for thermocouple inputs.

Mvt-50u Thermocouple Limitation

The Mvt-50u must be set (in Pocket Logger Software) to read either high or low temperatures.  When set for high temperatures, the low temperature limit is the ambient temperature of the Mvt Module.  When set for low temperatures, the high temperature limit is the ambient temperature of the Mvt Module.  The Mvt-11b and Mvt-22b do not have this limitation.
