Compact 75 mm three-wire float switch for highly accurate and repeatable single point level sensing and control. Polypropylene float cell, hermetically sealed, with CPE rubber cable and no mercury or lead. Ideal for water, sea water, most acid and alkali solutions and effluent or sewage: the teardrop float has no shoulders or edges for solids to build on. -
Mining/industrial-grade trailing-wire switch in a billet-aluminium housing with 1" 316 stainless steel process connection, for harsh mining applications. Suits open discharge applications and pipes from 50 mm (2") upwards. Tolerates high pressure, abrasive slurries, sewage, fibres, and high flow velocities. Built-in manual override. -
Uses a flexible stainless wire sensor rather than a paddle to detect flow. Suits open discharge applications and pipes from 50 mm (2") upwards. Ideal where solids or semi-solids are present — sewage pumping, slurry, mining, and high-velocity normal pumping where paddles foul or fatigue. -
Built tough for the most arduous industrial and mining applications. Rugged but highly-sensitive paddle switch with a billet-aluminium housing and a one-piece 316 stainless steel process connection. 400 bar pressure rating, manual override built into all models. -
Tough, highly-sensitive paddle switch for both hot and cold liquids. Magnetic repulsion drive (no seals, diaphragms or bellows) gives a high-pressure switch with no points of potential failure. Polypropylene or 316 stainless process connection; 3/4" or 1" BSP/NPT. -
Magnetically actuated piston switch with a solid machined 316 stainless-steel body — 200 bar pressure rating, handles liquids up to 90 °C. Ideal for hot/cold water pressure boosting, gravity hot-water systems, safety showers and other high-reliability applications. -
Rugged all-position flow switch for liquids in 15 mm to 25 mm (1/2" to 1") diameter pipes — up to 100 L/min. Detects continuous or pulsed flows; no metal parts in contact with the liquid. The P25-S model includes a heavy-duty mechanical switch + manual override for direct control of pump motors (motor load 8.3 A at 250 VAC, UL 2 HP). -
Simple, reliable inline flow switch for liquids or gases in tubes and small-diameter pipes. Detects continuous or pulsed flows, with no metal parts in contact with the liquid — ideal for sea water, ground water, acids and chemical solutions. -
Super-sensitive version of the popular P20 inline flow switch — detects flows under 350 mL/hour. Pure-mechanical, magnetically-actuated, with no metal parts in contact with the liquid; ideal for monitoring chemical metering pumps, water treatment, cooling towers, and other low-flow industrial processes. -
Compact inline flow sensor designed to detect very low flows — less than 500 mL per hour. Ideal for loss-of-flow detection in chemical metering and injection systems. PVC body with Viton seals; suits commonly used water-treatment reagents. -
Larger sibling of the C15 — 1" BSPT/NPT brass body switch for medium-flow applications. Versatile, magnetically actuated, normally-off; switches on in response to flow. Ideal for clean-liquid applications including pressure boosting and the control of pumps or fans via a relay, contactor or PLC — in fresh water, sea water and diesel fuel. -
Versatile magnetically-actuated normally-off flow switch in a one-piece brass body. Switches on in response to flow. Ideal for clean-liquid applications including pressure boosting and the control of pumps or fans via a relay, contactor or PLC — in fresh water, sea water and diesel fuel.
