Technical and Scientific Equipment have presented the GM 80-PA measuring amplifier with data logger, from Lorenz Messtechnik. The GM 80-PA measuring amplifier processes strain gauge signals of 0.35 mV/V to 3.3mV/V and active signals of 0V to ±1V, 0V to ±5V and 4mA to 20mA in sensors. The GM 80-PA measuring amplifier is available in Australia and New Zealand from Bestech Australia .
A high measuring accuracy (0.1% full scale ±1 digit) and fast measuring rates (up to 1000/s) are ensured by the employment of high precision amplifiers and components, a 16 Bit A/D converter and a fast micro-controller. A versatile, configurable data logger stores up to 3000 measured values with date. These measured values can be transferred to a computer by the RS232 interface.
Ten parameter sets are also available for sensors. In each case, the calibration data, the sensor designation and physical unit are deposited. Functions such as tare, fetch min-max, and delete min-max are available during the measurement. Using 3 opto couplers, control input functions such as data logging, issue of interface, delete buffer, tare or second limit value set can be addressed externally.
