Product Description

SSt Sensing Limited LLC500D3 OPTOMAX LLC500 Series Liquid Level Switch is a threaded mount sensor featuring polysulfone housing and polytetrafluoroethylene gasket. Designed for precise liquid level sensing in industrial, laboratory, and automation environments, it operates reliably within temperature ranges of -25°C to 80°C and pressures up to 20 bar.

This liquid level switch provides reverse polarity, electrostatic discharge (ESD), and transient over-voltage protection ensuring durability in harsh environments. Its push-pull output can sink or source up to 100mA, enabling direct drive of small loads with optional fail-safe PWM output capability. The wide supply voltage range supports flexible system integrations.

The solid-state construction eliminates moving parts, enhancing reliability and reducing maintenance. Its compact size enables installation in tight spaces, making it ideal for leak detection and precise liquid measurement. Internal or external mounting options and high pressure ratings extend suitability to diverse fluids and chemicals.

The device’s repeatable switching point and fast response provide consistent performance. Built-in output delays can be configured to mitigate false activations caused by liquid movement or sloshing.

Threaded mount liquid Level Switch with polysulfone housing and PTFE gasket. Reverse polarity, ESD, and transient over-voltage protected. Push-pull output supporting up to 100mA with optional fail-safe PWM. Operates from -25°C to 80°C and maximum pressure 20 bar.

Solid-state design with no moving parts ensures longevity. Compact form factor suitable for limited space installations. Repeatable switching point and configurable output delays.

Commonly applied in industrial automation, process control, water treatment, chemical processing, and laboratory systems where reliable liquid level monitoring is critical.
