Products

Circuit platforms built around your application.

Two focused product lines, each engineered as a customisable foundation for measurement and equipment electronics.

Electromagnetic Flowmeter Circuit

Measurement electronics for conductive liquids — coil excitation, electrode signal conditioning, processing and output.

Coil excitation. Controlled, typically pulsed-DC or low-frequency alternating coil current to create a stable magnetic field while avoiding the polarisation effects of steady DC.
Electrode front-end. High-impedance, high-CMRR differential acquisition designed around electrode characteristics, cable length and the liquid's conductivity range.
Synchronous processing. Sampling aligned with the excitation phase so that settled signal windows are measured and offset drift is rejected.
Outputs & interfaces. Analog current loop, pulse/frequency outputs, digital communication and local display options as required by the instrument.

Transducer drive electronics with frequency control, power regulation, timers and protection for cleaning equipment.

Power stage. Switching power stage (e.g. half-bridge or full-bridge topology) with an output transformer and matching network sized for the transducer array.
Frequency control. Operating frequency set and tracked around transducer resonance; optional sweep to reduce standing-wave effects in the tank.
Power regulation. Adjustable power level and soft-start so the system behaves predictably across load and liquid conditions.
Protection. Over-current, over-temperature and abnormal-load handling to protect switching devices and transducers.
