3. Coriolis mass flow meters
3.1 Description of the TM, TMU, and TM-SH sensors
The TM* series of sensors have an “Intrinsic safety” type of protection which is equipped with the following four
independent potential-free circuits:
Excitation circuit
Sensor circuit 1
Sensor circuit 2
Temperature sensor circuit (RTD)
All circuits within the sensor possess a safe separation.
When remote mounted, the transmitter should be connected to the sensor using a dedicated cable specially
designed for this purpose. Such a cable can be purchased from Heinrichs Messtechnik during your order
process.
Although the appearance of the standard and explosion-proof transmitters are often identical and their rating
plates contain similar information, under no circumstances should a standard (non-explosion proof) transmitter
be connected to an explosion-proof sensor!
3.2 Device identification
The rating plates on Heinrichs Messtechnik flow meters that are suitable for use in potentially explosive
atmospheres are labeled accordingly. Since the sensor and transmitter have different ratings, each device has
its own rating plate.
3.2.1 TM/TMU/TM-SH rating plate
The rating plate contains all the information necessary to identify the sensor, and for determining it’s suitability
for a potential explosive atmosphere.
Image 1: TM-T for process temperatures ranging from –20 °C to 100 °C.

For Explosion Flow-meters
3.3 Mounting
The mounting instructions for the standard sensor also apply to the explosion-proof sensor.
3.3.1 Thermally insulated sensor
The sensor may be outfitted with thermal insulation, also in explosive atmospheres. However, so not to impair
the junction box or connectors thermal ratings, the insulation shall only cover maximum the half of the sensors
neck onto which the junction box or connector is mounted.
3.3.2 Heated sensor
The sensor can be externally heated to avoid crystallization in the flow tube. Any heating technique or device
can be used. When using electrical heating devices, these must be suitable for use in the potentially explosive
environment present.
It is the operator’s responsibility to ensure that the heating temperature does not exceed the maximum
allowable temperature for the fluid and/or the maximum allowable temperature range for the potentially
explosive atmosphere in which the device is being operated.
The maximum allowable temperature range for the fluid is indicated on the sensors rating plate.
It is also the operator’s responsibility to ensure that no hazards are created by hot surfaces pursuant to
EN 1127-1 (Explosive atmospheres –Explosion prevention and protection) paragraphs 5.2 and 6.4.2.
3.3.3 Connection remote sensor –transmitter
A dedicated cable SLI2Y (SP) CY 5 x 2 x 0.5 mm² [blue] or similar is to be used for the electrical connection
between sensor and the remote mounted transmitter. This cable, which is available from Heinrichs
Messtechnik, has five twisted pairs, each of which has a foil shield, tinned copper mesh and filler cord. The
tinned copper meshes are installed in the “shield” terminal in both the sensor and transmitter. All 5 cable pairs
are shielded by a further tinned copper wire mesh. This external cable shield is connected to the housing via a
dedicated EMC cable fitting, thus ensuring optimum noise immunity.
