Average 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
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.
Average Temperature Converter
The MCG 2350 is a stand-alone average
temperature converter. Accepting its input from
an average temperature probe with up to 14
elements, the unit multiplexes these inputs to give
a digital output that corresponds to the product
temperature. The MCG 2350 is available in two
resolution ranges (0.1° C and 0.01° C). The housing
is an explosion proof enclosure and includes a
critical intrinsic safety (I.S.) barrier, allowing for
the use of either explosion proof probes or I.S.
probes. The MCG 2350 is normally connected
directly to other L&J Engineering models via a
serial connection, to give the transmitter average
temperature capabilities. The MCG 2350 is UL/CUL
and ATEX/CENELEC Approved.
