Rosemount 3100 Series Ultrasonic Level
Transmitter External Temperature Sensor
Part No : 03100-0001-0001
For use with ultrasonic transmitters 3102 and 3105
Introduction
For transmitter installations where
the integral temperature sensor is
not representative of the air / medium
temperature in the process, the use
of the external temperature sensor
improves accuracy.
Sensor Specification
316 Stainless steel body with two
locknuts, M8 thread, 6 mm maximum
panel thickness. Sensor working
temperature -40 to 85 °C, cable
working temperature -20 to 80 °C.
Cable 5 m long, single twisted pair.
Note :
When connected to a 3105
intrinsically safe transmitter, this
sensor is classified as ‘simple
apparatus’ according to EN 50020
paragraph 5.4.
Temperature class T6,
-20 °C < Ta < 80 °C

Installation
1. Connect the two sensor wires to
terminals 7 and 8 of the transmitter;
polarity is not important. See diagram
below; also refer to Transmitter
Installation Manual.
Ensure use of a suitably IP rated
cable gland to maintain the IP rating
of the transmitter.
2. Mount the sensor between the
transmitter and the liquid level,
to measure the air / medium
temperature at a representative point.
3. Avoid allowing the sensor to
become submerged.
4. Do not mount the sensor near a
heat source or in direct sunlight.
5. For the optimum response to
temperature change, do not mount
directly onto a large thermal mass.

Level
6. To avoid false echoes, do not
mount the sensor directly in the path
of the transmitter beam.
7. The transmitter will automatically
detect and enable the sensor. Fine
adjustments to the temperature
calibration may be made; refer to the
Installation Manual supplied with the
transmitter.
