Sensor Instruments & Signal Conditioners

Every good load cell & torque transducer requires good instrumentation

Our indicators and signal conditioners offer a wide range of options to provide you with exactly the information you need. Signal conditioning modules are used to provide excitation to the cells, powering the strain gages and taking the output signal from the cell and sending it on to a data acquisition system, display, relays or other devices to view or process the information in rail mount or in line. We have available low voltage units specifically designed for the automotive industry that can handle down to a 9V supply.

Instruments / Signal Conditioners

Every good load cell & torque transducer requires a good instrument or signal conditioner to take advantage of the accuracy inherent in the force sensor. Interface offers a complete range of instruments and signal conditioners for most applications. The advantage of purchasing the Interface load cell or torque transducer and instrument or signal conditioner together is that they can be preprogrammed and/or calibrated for the specific load cells or torque transducers for which they are to be used. All Interface instruments and signal conditioners provide excitation to the cells, powering the strain gages. Installation time is significantly reduced. Interface also recommends that the cable accessory be purchase saving further time.

Load Cell Signal Conditioners

The signal conditioners take the mV/V output signal from the load cells and send it to a data acquisition system in the form of an analog 4 to 20 mA, voltage or USB signal. Selection of the signal conditioner will depend on whether it is preferable to have it internal or external to the load cell, output desired, available power source and whether intrinsic safety is required.

Load Cell Instruments

Interface instruments are self-contained and provide a display as well as an available output to a computer and or data acquisition system. The instrument is readily programmed from the front panel and can be set up to read in lbs, newtons, or kilograms of force. The key factors in selecting the right instrument are speed and accuracy. Most Interface instruments include a shunt calibration feature, which permits the instrument to be calibrated based on a known force provided on the Interface calibration certificate.

Load Cell Instrument Definition

A signal converter is an electrical device that takes a specific electric input signal such as voltage and produces a specific corresponding output signal in some other format such as current. A load cell signal converter, display or control instrument accepts the millivolt per volt (mV/V) output generated by the load cell's internal strain gage circuit(s) and either converts this inpyt voltage to a display typically scaled to reflect the measured force in engineering units, provides some preset control outputs and/or converts the input voltage to another analog form such as current or USB to better interface with other electronic devices.
