1.1.5. Design and functioning
TP-140D pressure transducer converts mechanical deformations into an electrical signal proportional to defor-
mations. Then, using data from non-volatile memory, made during calibration, calculates the pressure value. The result
is converted into a digital code and transmitted over the communication line.
The measured value of the load on the RS-485 communication channel is transmitted to the control module
MU-150 for recording data and transmitting them for display on the indicator of the Display Module.
1.1.6. Measuring instrument and tool
During installation, start-up and operation no special measuring tools are required.
For installation and maintenance of TP-140D, standard tools of a specialist are used.

2.1. Operational constraints
2.1.1 Ex rating in operating
To operate TP-140D is allowed for personnel who have studied this manual and have passed the appropriate
instructions and have the necessary tolerances for work in hazardous areas.
When operating the complex, it is necessary to be guided by:
- chapter 3.4 POT R M-016-2001 "Safety Regulations for the operation of electrical installations";
- the current rules of electrical installations
- requirements of pp this guide.
It is necessary to control device conditions and communication cables while operating.
If there are any mechanical damages of the DEL-150 and communication cables be-
tween them you should stop using them.
While operating it is forbidden to damage seals and open all devices included in the complex of electronic dy-
namometer DEL-150..
It is forbidden to connect and disconnect the connectors of connecting cables and grounding conductors with the
dynamometer on.
In case of malfunctioning, replace the faulty device with a good one, connecting it according to the documenta-
tion. After replacement, check the reliability of the connections and grounding of the modular buildings to the weight of
the lift. During operation, periodically check the status of communication cables. If a violation of the protective layer on
the cable lines is detected, immediately turn off the power supply and replace the damaged cable.
Do not allow the violation of the sealing devices. If faults are detected, switch off the power supply and replace
the faulty device.
If mechanical damage is found, remove the faulty device and send for a repair.

2.1.5. ТP-140D(VBI) Texturing Instructions
-pressure transducer is placed with using a T-connector made regarding the customer’s dimension, at
the place of logging on hose wrench of standard manometer (see figure 11);
-a lever position sensor is installed in a place that allows operation without damage at a distance of no
more than 5 mm from the movable part of the gear lever of the figure 11 view 2;
-commutation box is convenient to place on the tong lowest surface as you can see at figure 11 type 3;
Note: The readings of the pressure gauge when idling (when the rotor rotates)
may differ from the readings of the torque meter. Therefore, calibration should
be checked when the rotor is braked (there is no flow of working fluid through
the hydraulic motor) by changing the pressure in the hydraulic system.

-13 Pressure Transducer is placed at cone-shaped sealing BRS (2”) and fasten with a wrench as you can
see at figure 13;
-it is recommended to avoid strokes to pressure transducer enclosure while BRS fastening wrench;
-in order to avoid connector contamination, one has to mounter sensor with a connector down;
-do not divert towards the likely finding of people.
To prevent the failure of the pressure sensor during the operations of purging and
pressure testing of the manifold, it is necessary to replace the sensor by the plug (Fig.
12). Failure to comply with these requirements leads to the cancellation of the manu-
facturer’s warranty obligations for the restoration of TP-140D (M) andTP-140D(MA)
pressure sensors.
