Notes:

1. Manifold mounts available.
Consult factory.

2. 18˝ is standard. Specify lead
length in inches (max. 48˝).
e.g. -FL18 or -FL30.

3. 18˝ is standard. Specify
lead length in inches (max.
48˝). e.g. -EL18 or -EL30.

4. DIN connectors require -C
SPDT circuit.

5. Requires stainless steel

pressure fitting.

6. -SR will result in wider
deadbands and slower
response times.

7. Set Point must be within
Pressure Range selected in
Step 1.

-WM = Weather Pack Connector, Male

-DE = Deutsch Connector, Male, DT04 Series

6 Fixed Set Point (optional)

A. Specify set point -FS
(in PSI or BAR, see example)

7

B. Set Point Actuation
R on Rising Pressure
F on Falling Pressure
Example: -FS1BARF for 1 BAR Falling

Table 1 — Pressure Range Codes

or -FS20PSIR for 20 PSI Rising

For Circuit Codes -A, -B and -C

Pressure Range Code Pressure Range Accuracy* Average Deadband**

10 15-75 psi (1.0-5.2 bar) ±2.5 psi (0.17 bar) +3% of setting 5 psig (0.34 bar) +11% of setting

20 50-150 psi (3.5-10.3 bar) ±6 psi (0.41 bar) +3% of setting 15 psig (1.03 bar) +14% of setting

30 150-650 psi (10.3-44.8 bar) ±15 psi (1.03 bar) +3% of setting 25 psi (1.72 bar) +15% of setting

40 500-1750 psi (34.5-121 bar) ±25 psi (1.72 bar) +3% of setting 55 psi (3.79 bar) +16% of setting

* Accuracy and set point of units may change due to the effects of temperature.
** In certain applications deadband can be tailored and controlled to customer specifications. Consult factory for details.
