10-782-AC — Acetal 1-Pack

SKU: 10-782-AC  ·  Stock #5501339  ·  1-Pack · Single Unit
Acetal · 1-Pack

Detecting liquid level in petroleum-based fluids requires a material that won't swell, crack, or dissolve on contact. The 10-782-AC is the Acetal version of the ERECTA SWITCH foundation element — the same hermetically sealed magnetic reed switch, but constructed from Acetal (POM) for full compatibility with gasoline, diesel fuel, hydraulic oil, motor oil, and other hydrocarbon-based liquids. Thread it into your own mounting fixture or use it as the switching element inside any ERECTA SWITCH Acetal assembly.

Frequently Asked Questions

Common Questions About This Product

What is the difference between a float level switch and a liquid level sensor?

A float level switch like the 10-782-AC is a point-level device: a float rides the liquid and actuates a magnetic reed switch at a set height, giving a simple on/off signal — no power, no firmware, no calibration. "Sensors" usually means continuous measurement (ultrasonic, radar, capacitive). ERECTA SWITCH targets reliable discrete-point control.

What are the typical applications for the 10-782-AC?

The 10-782-AC is used for pump start/stop control, high-level overflow protection, low-level dry-run protection, and tank or reservoir level alarms in OEM equipment. The modular ERECTA SWITCH system is built into laundry, HVAC, water-treatment, hydraulic, and chemical-handling machinery.

What liquid chemistries is the 10-782-AC compatible with?

Choose the material to match the media: Polypropylene (PP) for general aqueous, acids, and bases; Acetal (AC/Delrin) for solvents, fuels, and hydrocarbons; Kynar PVDF (KR) for aggressive or harsh chemicals. Every ERECTA SWITCH model is offered in all three materials.

Is the 10-782-AC a point-level or continuous-level device?

The 10-782-AC is point-level — it provides a discrete on/off signal at a set height. For multiple switch points, use a multi-level extended-stem set (2-, 3-, or 4-level) instead of a single continuous sensor.

What mounting options are available for the 10-782-AC?

ERECTA SWITCH offers vertical top-mount, bulkhead, and extended-stem configurations, plus side-mounted single-point models. The mount style is part of the model number — select the configuration that matches your tank geometry.

How is the actuation level set on the 10-782-AC, and how accurate is it?

Point detection is repeatable and mechanical. The trip height on the 10-782-AC is set by the 10-715 Precision Nipple, ordered separately in 1-inch increments (1″–70″), so you place the switch point exactly where the application needs it.
