Key parameters
Approvals
UL listed class options; hermetically sealed elements for Div II class
Type
Watertight industrial pressure switch (Ashcroft L-Series / LP)
Switch
Precision SPDT or DPDT snap-acting micro switch; single or dual setpoints
Setpoint
Adjustable from 15-100% of range; fixed or adjustable deadband
Repeatability
+/-1% of span (typical temperature shift noted on datasheet)
Enclosure
NEMA 4X / IP66 epoxy-coated aluminum (L-Series)
Fits industrial pressure alarm and control where you need an Ashcroft L-Series (LP) switch—vacuum to about 3,000 psi class ranges, ±1% of span repeatability, SPDT or DPDT snap-acting elements, and a NEMA 4X / IP66 epoxy-coated aluminum enclosure.
Key advantages
- Ranges — Vacuum to ~3,000 psi class
- Repeatability — ±1% of span typical
- Switch — Precision SPDT or DPDT; single or dual setpoints
- Deadband — Fixed or adjustable options
- Enclosure — NEMA 4X / IP66 epoxy-coated aluminum
Typical applications
- Pump / compressor control.
- Water and wastewater pressure trips.
- OEM machine pressure interlocks.
Selection guide
- Range / diaphragm
- Single vs dual setpoint
- Fixed vs adjustable deadband
Common mistakes
- Ordering XP F-Series when NEMA 4X L-Series is enough (or vice versa).
- Wrong wetted materials.
- Setpoint outside adjustable band.
When to RFQ / what to tell us
- Range, materials, function.
- Quantity, ship-to.
