The CM Series are eddy current sensors, excellent for use in harsh industrial environments under high pressure and temperature conditions. The ceramic housing can be used as the pressurised component, there is no extra housing needed. All CM sensors are shielded. The combination of shielded coil and ceramic housing guarentees an universal use in limited space of machine parts. Measuring of lubrication gap of crankshafts is a typical application for the CM series. THE BASIC PRINCIPLE The principle of measurement bases on a DSP-driven oscillating circuit made up of the probe (inductance) and...

INSTALLATION ■ ELECTRICAL INSTALLATION Choose a dry location, preferably with a stable temperature for the electrical installation (TX-Driver) such as electrical cabinets,terminal boxes, housing, etc. Connect the supply line, probe lines and output lines. Please ensure that all supply and signal lines are laid separately from energy-carrying lines such as supply and discharge lines from converters and drives, lines from ovens and synchronised appliances or generator lines, etc., in order to avoid malfunctions in the signal behaviour. Please use shielded supply lines only and apply the...
