Bridge Completion Module BCM for GSV-2TSD and GSV-1T8 BCM for GSV-2TSD BCM for GSV-1T8 The bridge completion modules are used for supplementing quarter-bridges and halfbridges to full bridges. In the case of the measuring amplifier GSV-2TSD, the bridge completion module has the form of a 6-pole plug with 3 screw type terminals. The quarter-bridges or half-bridges are connected with the contacts of the 3 terminals. For the measuring amplifier GSV-1T8 as well as for other measuring amplifiers with 15pole sub-D input socket, the bridge completion modules are designed as sub-D plugs with 5m connecting cable. The bridge completion modules are available as 120 Ohm, 350 Ohm and 1000 Ohm modules. They are fitted with resistors of tolerance 0.1%, TK25.

The wires from terminals 4a and 4b resp. the brown and green wires are brought together at the soldering node of the external strain gage. The conductor resistance thus effects both the positive and the negative branch of the bridge circuit. Errors due to changes in conductor resistances and interferences are compensated thereby. If a three-conductor technology is not to be used, a short circuit bridge must be laid between 4a and 4b. At the bridge completion modules with connecting cable BCM-QB-S additionally the pin 15 is led through with a yellow connecting wire to enable shunt calibration, if necessary. Positive strain at R3 results in a positive output signal. Negative strain at R4 results in a positive output signal. 2 ME-Meßsysteme GmbH, Neuendorfstr. 18b, D-16761 Hennigsdorf Tel +49 3302 559 282, Fax +49 3302 559 141, info@me-systeme.de , www.me-systeme.de
