Technology choice 1
Magnetic float type
Electrical
Go Back
Magnetic float switches are simple high or low alarm switches of robust construction, making
them ideal for a wide range of industrial applications. In general terms, they are more suitable
for applications with higher temperatures or switching loads.
Electrical technologies offer small, light, robust and easy to install, options often with on-board
microprocessors, self-monitoring and fail-safe functions.

Flameproof EEx d
Intrinsically safe EEx i
Go Back
EEx d protection offers protection of electrical equipment in flammable atmospheres by
containment. EEx d equipment is generally robust and suitable for applications where
mechanical protection is also desirable.
EEx i intrinsically safe protection protects electrical equipment by power limitation, but places
few physical limits on the design and so is suitable for small or compact devices. An approved
power supply will be required.
Technology choice 5
Rotating Paddle
Go Back
Capacitive Probe
Capacitive Probes are microprocessor based, self calibrating level controls with no moving parts. The active
shield technology makes them ideal for sticky or products prone to build up.
Rotating Paddle Switches are robust, traditional level switches used in many “Primaries” Industries
