Lamb Industries M4-Series
Pressure/Snap Action
Switch |
  03 |
 |
The M4-Series pressure
switch features adjustable calibration, high electrical ratings (up to
16(4)A 250V), and is suitable for high pressures (800 - 5000 mbar) in many
different fluids including gases, air, and liquids, and was specifically
designed for steam. This is due to the seperation of the electrical and
pressure circuts. Hysteresis can be 10%-30% of the set point. The M3-Series
is a lower temperature version. Lower amperage, lower cost pressure switches
are availabe in the P1-Series and 79-Series |
