Resistance Temperature Detector
The Resistance Temperature Detector (RTD) measures multiple spot temperatures by outputting a resistance change to
a gauge or transmitter. This change in resistance, which is directly proportional to temperature, is detected by a precision
input bridge circuit in the transmitter. In addition to two element leads, a third reference lead is provided. The reference
lead is used to remove lead wire resistance from the measurement of the temperature elements.
Averaging Temperature Probe
The MCG 351 (ATP) represents state-of-the-art temperature measurement, and is accepted worldwide to use as a standard
for custody transfer inventory and corrected volumes. The MCG 351 Averaging Temperature Probe (ATP) allows gauges
and transmitters to sense temperature through the change of resistance in the probe. The MCG 351 possesses a series
of spot temperature sensitive elements positioned at different points in the probe. These resistors are at various levels so
that the average temperature of the product within the tank may be measured. The multiple element probe allows the
gauge to select the submerged elements and average their reading.
