Blickman SS106-120 Liquid Level Sensor

Blickman SS106-120 Liquid Level Sensor (LBL-OS200-120AC)

The Blickman SS106-120 Liquid Level Sensor (Manufacturer Part Number: LBL-OS200-120AC) is a heavy duty, precision constructed electro-mechanical fluid monitoring device for demanding industrial and maritime process applications. The sensor is ideal for high-vibration engine room applications and corrosive fluid handling systems. The sensor delivers absolute point-level sensing and continuous switching feed-back. This Blickman designed solution offers high-integrity tracking of liquid interfaces in pressurized or atmospheric containment structures, avoiding overflow or dry-run circumstances in essential auxiliary systems.

Engineer’s Guide:

When installing the Blickman SS106-120 in high-vibration machinery spaces—such as main propulsion auxiliary decks—always utilize flexible conduit fittings and vibration-dampening rubber gaskets on the mounting flange. Solid-mounting directly to high-amplitude vibrating bulkheads can induce premature micro-fractures in the internal reed switches or float arms.

1. Wiring & Isolation: Always route low-voltage signal cabling separate from heavy 440V/690V power lines to eliminate electromagnetic induction (EMI) interference on the 120V AC control loops.
2. Preventative Maintenance: For marine sewage or oily bilge applications, schedule a routine ultrasonic cleaning or manual flush of the float stem every 6 months to prevent mineral scaling or paraffin buildup from restricting float travel.

Frequently Asked Questions

What is the primary operating voltage of the Blickman LBL-OS200-120AC?

The sensor is designed for a nominal input rating of 120V AC, 50/60 Hz, making it fully compatible with standard auxiliary power control systems found on commercial vessels and industrial plants.

Can this sensor be used in corrosive chemical or saltwater environments?

Yes. The wetted components and housing are constructed from grade 316L stainless steel, providing exceptional resistance to marine salt spray, chlorides, and mild industrial chemicals.

How do I configure the output contacts for high or low-level alarm setups?

The internal switching element features SPDT contacts. By altering the terminal connections between the Normally Open (NO) and Normally Closed (NC) terminals, you can invert the logic for either high-level alarm cut-off or low-level pump protection.
