Tight tank layouts call for level control that fits quickly and does not complicate assembly. The ML series is built for applications where small size and simple installation matter, using one electrical contact for straightforward liquid level switching.
Polypropylene and PVDF versions cover different material requirements, with pressure ratings of 3 Bar or 6 Bar and temperature ratings of 90 °C or 130 °C depending on the selected type. Installation options include assembly from inside the tank with M16 x 1,5 body thread, from outside the tank with compression gasket, or threaded 1/2" and 3/4" versions.
The operating principle is simple and dependable: a permanent magnet in the float actuates a reed contact sealed in the body. Rotating the instrument by 180 degrees changes the contact behavior between N.O. and N.C. status. The series provides IP65 protection, cable or faston wiring options, and an ambient operating range of -30 / +55 °C at 90% RH.
A reed contact is sealed in the body, while a permanent magnet inside the float actuates the contact as the liquid lifts the float.A reed contact is sealed in the body, while a permanent magnet inside the float actuates the contact as the liquid lifts the float.
PML versions use polypropylene, while FML versions use PVDF. The source lists blue for PML and black for FML.
The series includes M16 x 1,5 body thread for inside-tank assembly, GC compression gasket mounting, and 1/2" or 3/4" threaded versions.
Threaded versions are available with conical UNI 7/1 or conical NPT thread, with brass, AISI-316, polypropylene or PVDF material options listed.
Electrical contact options include SPST and SPDT, with ratings defined for VA, W, AC, DC and current in the technical data.
Cable wiring is available as 1.5 m or 3 m. Cable length on request is listed, and male faston 2 x 0,8 is available only on 16K - GC versions.
Viton is listed as the standard gasket material, with silicon available on request.
The installation data specifies tank hole sizes, wall thickness limits and gasket positioning for inside and outside mounting
