Temposonics MH Analog ® Operating Manual 1. Product description and technology Temposonics sensors can be used in versatile mobile machines without any restriction and replace contact-based linear sensors like poten- ® tiometers. Highly dynamic systems are controlled safely by means of Temposonics sensors, thus enhancing the productivity, availability and ®...
Temposonics MH Analog ® Operating Manual 2. Temposonics MH series analog ® Temposonics MH series sensors are designed for hydraulic cylinders. With the analog output configuration they are qualified to operate on ® electronic controls of mobile machines. Sensors with different analog output signals (mA/ VDC) are suitable for applications on vehicles. 3.

Machine ground Cable shielding To ensure perfect operation of the sensor, the hydraulic cylinder must In the installed condition, the sensor is shielded sufficiently by the be connected to the machine ground. Equipotential bonding is often metal hydraulic cylinder. For this reason, no separate shielding is ensured by the mechanical contact between the cylinder and other taken via the M12 connector.

Temposonics MH Analog ® Operating Manual 5. Operation and function 5.1 Filter circuitry (noise) Any resistor causes for example thermal noise, which is more or less evident at the output of the circuitry if amplified accordingly. Additionally, external effects such as the supply voltage ripple or electro-magnetic fields in the immediate vicinity can affect the noise spectrum. To minimize noise, the use of a filter is mandatory with analog measurement.
Temposonics MH Analog ® Operating Manual 5.2 Set point tolerance zero to full scale At MTS, the sensor set points are calibrated with a tolerance of ± 1 mm. When installing in cylinders, please note that any additional tolerances must be taken into account. During teach-in, all tolerances in the cylinder-and-sensor system are eliminated. The piston rod drives towards the zero or full scale.
Temposonics MH Analog ® Operating Manual 5.3 Insulation checks Part of the testing performed on off-road mobile machinery can be insulation checks. During these checks, high voltages are applied to deter- mine the dielectric strength of the cables against the housing (insulation resistance). For testing, all connecting cables must be disconnected from the sensors.
Temposonics MH Analog ® Operating Manual 6. What should be done in the event of functional disorder? 6.1 Typical installation faults/consequences Cause Consequences Faulty pin allocation No signal Ambient temperature too high Possible damage to components – no sensor signal Component damage, because the sensor has been hammered Cylinder borehole too small down too violently.
Temposonics MH Analog ® Operating Manual 6.2 Checking the sensor function Analog sensors (current or voltage output and PWM) • Check the connections and the pin allocation • Check the supply voltage • Disconnect the sensor and test it in connection with an external power supply (e.g. car battery) • Use a Temposonics test unit. The operating instructions of the test unit are ® available for downloading from the log-in area under www.mtssensor.com • Use the multimeter in accordance with the explanation.

Temposonics MH Analog ® Operating Manual Measuring the VDC output signal Use a multimeter and select the VDC multimeter measuring range to measure the output signal (0.25 – 4.75 VDC; 0.5 – 4.5 VDC and 0.5 – 9.5 VDC). Connect the multimeter with the green signal conductor and the white 0 V conductor. Connect the supply voltage (+12/24 VDC) to the brown conductor and O V (-0 V) to the white conductor.
