Page 3: General Information
To ensure reliable and safe operation, the measuring amplifier must be operated in compliance with the specifications according to this technical description only. These regulations must also be observed if using accessories, that have been ordered from Althen Mess- & Sensortechnik GmbH together with the measuring amplifier. -
Page 4: Instructions For Use Of The Measuring Amplifier
Notice: Changes of the amplifier of any kind demands for the explicit approval of Althen Mess- & Sensortechnik GmbH. Changes of any kind done without that approval exclude all possible warranty and/or liability of Althen Mess- & Sensortechnik GmbH. -
Page 5: Instructions For Use Of Strain Gauge Sensors
2.1 Instructions for use of strain gauge sensors Notice: Strain gauge sensors with a small range are extremely sensitive to improper handling. Force transducers can be destroyed simply by touching. Same applies for the diaphragms of pressure transducers. So, bear in mind: handle with care! Loading the transducer in excess of the nominal range may result in an increased and lasting zero balance offset as well as damage to the sensor. -
Page 6: Terminal Assignment
4 Terminal assignment The electrical connections are made via cable glands to terminal blocks inside. The terminal numbering can be found on the pcb. The maximum cable cross-section is 2,5 mm². The EMC-installation instructions must be complied with. Clamp Description Clamp Description +Supply voltage (+Ub) -
Page 7: Strain Gauge Excitation Voltage
4.2 Strain gauge excitation voltage The described measuring amplifier is able to supply one strain gauge transducer. Any strain gauge full bridge with a bridge resistance of 300 ohms or more may be connected. The transducer can be supplied with either 10 VDC or 5 VDC unipolar voltage. This value can be selected with a solder point (LP-01) for coarse, and with a potentiometer (P-05) for fine adjustment. -
Page 8: Analogue Output Current
4.3.2 Analogue output current The analogue current output can be picked up on the corresponding clamps. See chapter 4 “Terminal Assignment”: The analogue current output is not capable of going below 4 mA, therefore when adjusting the designated zero-point, the output signal has to be set slightly higher than that, just in order to check if said signal does not virtually hang below 4 mA. -
Page 9: Zero Point Adjustment Range
5.1 Zero point adjustment range It is to be noted that there is a slight dependence between zero-point adjustment and amplification (gain). The zero-point adjustment range is approx. ± 10 %. This range can be changed by setting the dip-switch according to the table below: S01-1 S01-2 S01-3... -
Page 10: Adjustment / Calibration Of The Amplifier
5.2 Adjustment / calibration of the amplifier In order to adjust or calibrate the amplifier at least one multimeter has to be connected to one of the analogue outputs. Preferably analogue output voltage. Notice The calibration of the amplifier in general is done with the potentiometer P-02. This basic calibration adjusts the analogue voltage output. -
Page 11: Correction Of The Analogue Current Output
5.2.1 Correction of the analogue current output The minimum of analogue current output is 4 mA. A lower current is not possible. When calibrating, the zero-point current has to be set to 4,1 mA with the potentiometer “NULLPUNKT”. Now the range of the current output can be set to 16 mA by using the potentiometer P-03. -
Page 12: Maintenence
Amplifiers and measurement units manufactured and sold by Althen Mess- & Sensortechnik GmbH serve B2B purposes only. Therefore, those old appliances must not be given to the communal disposer, but must be given back to the seller or disposed of properly. -
