2.Customer specific types

Minimum batch size: 100 pieces

Switching points

The differential of factory set switch points can be adjusted within the limits given in the charts on page 4 to 6. Use the recommended lower switch point line in working envelope for optimum results.

Example:

Step 1: Select your desired upper switch point P1. Draw a horizontal line to cross the upper switch point line.

Step 2: Draw a vertical line from this intersection point.

Step 3: Select your desired switch point between P2 and P4.

Notes:

1.Specify always upper and lower switching points for pressure switch with automatic reset function.

2.Specify only cut-out switching point for pressure switch with manual reset function.

3.For versions with micro-switch only one switching point can be adjusted while the second switching point is determined by the fixed differential of the micro-switch (see Pressure Ranges on page 2).
