The Model 142 low-noise inline strain gage amplifier includes an auto-zero function that promises extreme measurement accuracy. A patent-pending feature, the auto-zero function initiates right before measurement either using a push-button or remotely via a grounding pin. This function provides a zero reference within ±1.5 mV of true zero as well as corrects for zero errors due to mounting stresses or misalignment. Long term drift errors are corrected in real time so the device is zeroes out prior to operation. In a 57 mm x 25.4 mm x 14 mm anodized aluminum case, the Model 142 is factory-configured to interface with a 350Ω strain gage. Users can change an internal resistor to match a different type of strain gage. For more details, contact Bob Arkell at 760-466-7614 or [email protected]
