Liquid Low Flow Alarm | Platon DS1431

Liquid Low Flow Alarm - Overview

Suitable for liquid low-flow or flow-failure alarm on cooling systems, water heaters or lubrication systems. This rugged sensor has a simple electrical reed switch output. Installed in a vertical line with flow upwards, the normal flow lifts the float in the sensor. A magnet encapsulated in the float then actuates a reed switch, giving contact closure. Should the flow drop to below the preset alarm level, the float falls to the rest position and the contacts open to give an alarm output. Available in 1/2” and 3/4” line sizes, with BSP female threaded connections. Alarm rates are factory set between 0.5 L/min and 10 L/min to suit most applications. The standard unit is brass and has a one-piece body suitable for high pressures, with no glands or seals to leak. The externally mounted reed switch has flying leads for local connection to a terminal block. Typical applications include water supply flow failure into heaters or boilers (where the flame or power supply is cut to prevent overheating accidents), for lubricant or cutting fluid flow failure in machine tools or gearboxes. For flow failure alarm in cooling circuits, the LF flowswitch is used on X-ray equipment, electron microscopes, transformers, radio transmitters and high frequency generators.

Adjustable Plastic Paddle Flow Switch | Platon DS1401

Adjustable Plastic Paddle Flow Switch - Overview

This paddle flow switch is ideal for protecting unattended equipment from damage or loss of production. Operation is simple and dependable. In most applications, the switch is usually off when there is sufficient flow of liquid or air. When the flow stops, the vane spring moves the vane, actuating a single pole double throw switch rated at 5A 120/250Vac to start or stop a motor, pump, or engine, or to operate a damper or valve; shut down a burner or actuate an alarm or signal. It has a leakproof body and vane constructed of tough durable Polyphenylene Sulfide and has excellent chemical resistance. The full-size trimmable vane is provided with moulded-in graduations allowing for installation in pipes ranging from 1 inch to 6 inches in diameter. The control is recognised as an industrial motor controller per UL standard 508 and is suitable for mounting in a protected environment. Applications include chemical processing, air conditioning, refrigeration, heating systems, cooling systems, machinery, liquid transfer systems, water treatment, food processing and machine tools. An IP 65 connection head option is available for weatherproof applications.

Hot Wire Thermal Flow Switch | FTC05

Hot Wire Thermal Flow Switch - Overview

Based on the thermodynamic principle, this flow switch features two temperature sensors inside the probe: one is for the medium temperature into which it projects, and the other one is heated a few degrees above the medium temperature. When the medium flows, the heat generated in the sensor is diffused by the medium. The difference between these two sensors is used to measure flow rate. It comes in all-metal housing and is suitable for a variety of pipe diameters.

Hot Wire Thermal Flow Switch - Features
- Suitable for oil, water, gas, and liquid level detection
- Selectable output: PNP/NPN/Relay
- Metal shell design
- Easy installation
- Measuring rod withstands pressure of 10 bar (length can be customised)
- LED light indicator, simple shape
- Can set the switch point or range

2-Way Diaphragm Valve | Type 514-519

2-way Diaphragm Valve - Overview

Diaphragm valves are used for regulating, controlling, closing, and monitoring volume flows. This is especially useful when transporting contaminated, aggressive or abrasive media. This type of valve has distinctive advantages due to its simple function and optimised design. Only the valve body and diaphragm come into contact with the medium. The valve is suitable for use with gases and liquids and can be used in any location and drained completely. Unlike other Valve Types, no pressure surges can be caused by closing the diaphragm valve. This Valve Type comes as a manually operated valve or an automatic valve.

2-way Diaphragm Valve - Features
- Complete plastic valve - no metal screws
- No corrosion in aggressive media/environment
- Constant leak-tightness
- No need to re-tighten
- Highly stable connection of upper part and valve body using buttress thread
