Electrical Signal

Select a sensor or instrument by input or output signal type.  Measure or transmit current, voltage, RS232, RS485, USB, solenoid relay switch and logic switch.

Specify your instrument output signal requirements

Instruments which convert a physical measurement or electrical signal and transmit it as a variable series current loop output signal.

Instrumentation with an output which is converted from a transducer or electrical signal to an amplified dc voltage output signal.

Sensing devices with a wheatstone bridge strain gauge circuit that produces a low voltage mV signal without any amplification. Select a device with a output sensitivity that is proportional to the input supply voltage.

Instrumentation with RS232 digital communications for connecting to industrial computers, desktop PC and other microprocessor equipment with serial bus interface cards.

Instruments with RS485 serial coms for linking to digital electronics or with multiple RS485 serial devices.

Instrumentation with a universal serial bus (USB) digital connection for use with PC computers.

Electronic devices which include voltage free contact relays for switching of high voltage or current signals.

Devices which have a switchable low voltage output for providing a logic based on/off control signal.

Instrumentation for measuring 4 to 20 mA current loop output and displaying the scaled reading in the desired engineering units or retransmitting via a digital or analogue retransmission channel.

Instruments for the measurement, display or retransmission of DC voltage input signals.

Instrumentation for signal conditioning low voltage inputs from wheatstone bridge strain gauge sensors. Measure millivolt input levels and display in the relevant engineering units or amplify the signal and retransmit as a voltage, current or digital signal.
