Transmitters
Industrial transmitters convert, display and transmit the measurement signals taken on your production lines (flow, pressure, temperature, level).
By converting the measured physical quantity into a standard signal (4-20 mA, 0-10 V or fieldbus), they enable your PLCs and controllers to run your processes with consistent accuracy.
Discover a wide range of refurbished, overhauled and tested transmitters from major instrumentation manufacturers (Siemens, Endress+Hauser, Krohne, Yokogawa) to keep your measurements reliable without replacing your entire instrumentation loops.

FAQ
The transmitter acts as the interpreter between the physical sensor immersed in or mounted on the process and the control system (PLC/DCS). It conditions the raw sensor signal, filters out noise, applies calibration coefficients and transmits a usable digital or analog value for control.
Faults most often appear as a frozen output signal (e.g. stuck at 4 mA or 20 mA), drifting measurements, a blank local display, fieldbus communication errors or the inability to set the zero point.
In most modular architectures, yes. You can replace the faulty transmitter head or remote electronics housing while leaving the mechanical measuring body in place, which avoids draining the installation or breaking the process seal.
Every refurbished unit is connected to a calibrated signal simulation bench. We check the accuracy of the current/voltage outputs, stability under temperature variations, correct operation of the local display and the configuration of the measurement parameters to ensure a direct restart on your site.
