Texense Strain Gauge Amplifier XN2.1 allows programmable functions without computer
04 October 2009
Texense International Company, specialist of robust sensors for embedded measurement introduces a new product. The Texense XN2 is a PCB analog strain gauge amplifier, with high resolution and high speed, with offset and gain adjusted by microcontroller. Because of its small size, the Texense XN2 may be bonded close to the gauges, which will reduce noise on the signal.
When the amplifier is wired to the strain gauge bridge, the customer may, with a single VPROG signal (no use of a computer):
- adjust the offset
- adjust the gain by applying an effort on the part
- start a self training cycle for temperature compensation
- adjust temperature gain compensation depending on part and gauge materials
- check the gauge bridge state
The Texense XN2 simplifies strain gauging because it doesn’t need zeroing, nor temperature compensation for offset or sensitivity. Just bond 1, 2 or 4 gauges on the part, wire them to the amplifier and it will do the job !
| Supply voltage: | 5 to 16 V, Supply current: 3.5mA (18mA total current with a 350 ohms full bridge) |
| Operating Temperature: | 0° to 120°C |
| Dimensions: | 13 x 10 x 3.2 mm |
| Bridge supply voltage: | 5V (internal) Bridge gauge impedance : 120 to 1000 ohms |
| Offset: |
Adjustable from 0.5V to 2.5V (factory default value : 2.5V) Max initial recommended bridge unbalance: +/- 2mV for 350 ohms gauges (0.6mV for 120 ohms, 5mV for 1 Kohms). If more, the offset tuning will not be independent of the gain. |
| Gain: | From 70 to 1250 (factory default value : 200) Temperature compensation set by a single resistor “R Metal” depending on part and gauge material |
| Output signal: | 0 to 5V Cut off frequency : default 90Hz (1 pole filter), adjustable up to 8KHz Offset drift with temperature : < 10mV |
