Bestech Australia present the model A2 heavy duty sensor signal conditioner from BCM Sensors. This signal conditioner is suitable for any sensor or transducer, which uses a Wheatstone bridge strain gauge circuit.
When connected to a 12 to 30V DC power supply, the sensor signal conditioner provides a constant excitation voltage to the Wheatstone bridge circuit of the sensor, and amplifies the output signal to standard ranges (e.g. 0 to 5V DC or 4 to 20mA), for further transmission to a PLC.
The A2 signal conditioner is excitation voltage adjustable with a built-in potentiometer, and is capable of handling 8 parallel-connected sensors of 350? bridge resistance. The A2 signal conditioner is also gain and zero adjustable. Accuracy is typically 0.1% of the full scale output, while the operating temperature range is between -20°C and 85°C.
The A2 signal conditioner is situated in heavy-duty aluminium housing with anodised surface treatment. The rubber-seals between the housing cover and container, and the waterproof cable gland ensure that the signal conditioner is protected to an environmental rating of IP 66. The unit can easily be fixed to the panel mounting plate through two waterproof holes, which are hidden inside the housing.
