Mounting diagram
Calibratable temperature measuring transducer THERMASGARD® TM 54 with eight switchable measuring ranges and continuous output, with connecting head made from aluminium (optionally with cable gland or M12 connector according to DIN EN 61076-2-101) and straight protective tube. A basic unit in four variants through combination with accessories, eg, for robust applications with a separate immersion sleeve made from stainless steel. The duct sensor is used to detect temperatures in liquid or gaseous media. It is used in pipes, heating engineering, storage systems, compact district heating stations, warm and cold water systems, oil and lubrication cycle systems, mechanical, apparatus and plant engineering and throughout the industrial sector. The sensor is factorycalibrated; an environmental precision adjustment by an expert is possible.

Measuring transducers, calibrateable, with active output TEMPERATURE
RANGES:
When selecting measuring transducer ranges, it is necessary to ensure that the maximum temperatures permissible for sensor ⁄ enclosure are not exceeded ! Ambient temperature for measuring transducers: – 30 …+ 70 °C
- Apparent ohmic resistance = see load resistance diagram
SUPPLY VOLTAGE :
For operating voltage reverse polarity protection, a one-way rectifier or reverse polarity protection diode is integrated in this device variant. This internal one-way rectifier also allows operating 0 – 10 V devices on AC supply voltage. The output signal is to be tapped by a measuring instrument. Output voltage is measured her against zero potential (O V) of the input voltage! When this device is operated on DC supply voltage, the operating voltage input UB+ is to be used for 15…36 V DC supply and UB – or GND for ground wire! When several devices are supplied by one 24 V AC voltage supply, it is to be ensured that all ”positive“ operating voltage input terminals (+) of the field devices are connected with each other and all ”negative“ operating voltage input terminals (–) (= reference potential) are connected together (in-phase connection of field devices). All outputs of field devices must be referenced to the same potential! In case of reversed polarity at one field device, a supply voltage short-circuit would be caused by that device. The consequential short-circuit current flowing through this field device may cause damage to it.
Therefore, pay attention to correct wiring!
Installation and Commissioning
Devices are to be connected under dead-voltage condition. Devices must only be connected to safety extra-low voltage. Consequential damages caused by a fault in this device are excluded from warranty or liability. These devices must be installed and commissioned by authorised specialists. The technical data and connecting conditions shown on the device labels and in the mounting and operating instructions delivered t ogether with the device are exclusively valid. Deviations from the catalogue representation are not explicitly mentioned and are possible in terms of technical progress and continuous improvement of our pro ducts. In case of any modifications made by the user, all warranty claims are f orfeited. Operating this device close to other devices that do not comply with EMC directives may influence functionality. This device must not be used for monitoring applications, which serve the purpose of protecting persons against hazards or injury, or as an EMERGENCY STOP switch for systems or machinery, or for any other similar safety-relevant purposes. Dimensions of housing or housing accessories may show slight toler- ances on the specifications provided in these instructions. Modifications of these records are not permitted. In case of a complaint, only complete devices returned in original packing will be accepted. Our “General Terms and Conditions for Business“ together with the “General Conditions for the Supply of Products and Services of the Electrical and Electronics Industry“ (ZVEI conditions) including supplementary clause “Extended Retention of Title“ apply as the exclusive terms and conditions“.
Notes regarding mechanical mounting and attachment:
Mounting shall take place while observing all relevant regulations and standards applicable for the place of measurement (e.g. such as weld-ing instructions, etc.). Particularly the following shall be regarded:
- VDE ⁄ VDI directive technical temperature measurements, measurement set – up for temperature measurements.
- The EMC directives must be adhered to.
- It is imperative to avoid parallel laying of current-carrying lines.
- We recommend to use shielded cables with the shielding being attached at one side to the DDC ⁄ PLC.
- If the sensor is used in refrigeration circuits, it must be insulated together with the housing to reduce the temperature potential between the device and the medium to a minimum and thus prevent condensation damage.
Before mounting, make sure that the existing thermometer‘s technical parameters comply with the actual conditions at the place of utilization, in particular in respect of:
- Measuring range
- Permissible maximum pressure, flow velocity
- Installation length, tube dimensions
- Oscillations, vibrations, shocks are to be avoided (< 0.5 g)
Attention! In any case, please observe the mechanical and thermal load limits of the protective tubes according to DIN 43763 or according to specific S+S standards!
Notes regarding process connection of built-in sensors:
If possible, select material of protective tube to match the material of
piping or tank wall, in which the thermometer will be installed! Maximum
temperatures Tmax and maximum pressures pmax are as follows: for TH – MS brass
sleeves Tmax = +150 °C, pmax = 10 bar and for TH – VA stainless steel sleeves
(standard) Tmax = +400 °C, pmax = 40 bar.
Screw-in threads:
Ensure appropriate support of the gasket or sealing material when mounting!
Permissible tightening torque standard values for screw – in threads, are as
follows:
- M 18 x 1.5; M 20 x 1.5; pipe thread G ½ ” : 50 Nm
- M 27 x 2.0; pipe thread G ¾ ” : 100 Nm
Flange mounting:
In case of flange mounting, screws in the flange part must be equally
tightened. The lateral pressure screw must clamp securely, otherwise the
feeler shaft might slip through.
Welding sleeves:
Specific welding instructions shall be observed. On principle, unevenness or
the like that might influence the system‘s ”CIP ability“ must not develop at
welds. For high-pressure lines, pressure test certifications and inspections
are required.
Notes on commissioning:
This device was calibrated, adjusted and tested under standardised conditions.
When operating under deviating conditions, we recommend performing an initial
manual adjustment on-site during commissioning and subsequently at regular
intervals.
Commissioning is mandatory and may only be performed by qualified personnel!
Permissible approach velocities (flow rates) for crosswise approached
protective tubes in water.
The approaching flow causes protective tube to vibrate. If specified approach
velocity is exceeded even by a marginal amount, a negative impact on the
protective tube’s service life may result (material fatigue). Discharge of
gases and pressure surges must be avoided as they have a negative influence on
the service life and may damage the protective tubes irreparably.
Please observe maximum permissible approach velocities
for stainless steel protective tubes 8 x 0.75 mm (1.4571) (see graph TH – VA ⁄
xx, TH – VA ⁄ xx ⁄ 90) as well as for brass protective tubes 8 x 0.75 mm (see
graph TH – ms ⁄ xx) :
