FS926E Gems sensors precision piston-type flow switches – Ultra low flow set points

Stock No:

Manufacturer

The Gems FS-926E Series is a precision low-flow piston-type flow switch designed for very low liquid and gas flow detection. It incorporates a double-piston design, enabling detection of flow rates as low as 50 cc/min, making it ideal for leak detection, chemical dosing, gas sampling, and semiconductor cooling applications.
  • Ultra-low flow detection — liquid flow settings from approximately 0.05 to 0.30 L/min (50–300 cc/min).
  • Piston operating principle — a specially designed low-flow piston provides reliable switching at very low flow rates.
  • Fixed flow set point — factory-set for the required flow rate.
  • SPDT switch output — provides a changeover contact for alarm, pump protection or control applications.
  • 1/4″ NPT female process connection. BSP for Thread for FS926E model
  • Brass or 316 stainless-steel construction options.
  • High pressure capability — up to 1,000 psi operating pressure, depending on configuration.
  • ±10% set-point accuracy.
  • Compact design suitable for equipment protection and OEM applications.
  • Suitable for liquids and gases.
  • Typical applications include cooling-water monitoring, lubrication systems, chemical injection, gas sampling, leak detection and
  • semiconductor/electronic equipment protection.
  • 50-micron filtration is recommended to protect the piston mechanism from contamination.

TTPFS30 Trantech mechanical paddle flow switch

The Trantech TTPFS30 Mechanical Paddle flow switch designed to detect the presence or absence of liquid flow in pipelines. Operating on a simple mechanical paddle principle, the switch is actuated by the movement of liquid against the paddle, providing a dependable SPDT microswitch output for pump protection, equipment interlocking, alarm indication, and process control. The adjustable paddle can be trimmed to suit a wide range of pipe sizes, making the TTPFS30 suitable for water, cooling systems, hydraulic circuits, lubrication systems, and general industrial process applications.

FS-107E – Adjustable

The FS-107E model operates in any mounting position. It is equipped with a calibrated piston in a calibrated orifice for viscosity compensation over 1 to 600cSt. The piston is displaced by flow to magnetically actuate a sealed hermetic reed switch. When flow decreases a postive spring returns the piston to its prior position and de-actuates the reed switch. The reed switch assembly is movable to allow for customer setting of flow rate within the limits of the switch selected. The adjustment does not effect the flow path, therefore pressure drop is not influenced when changing set points. Robust components allow a pressure of 250 bar, ideally suited for high pressure lubricated systems.

FS-925(E)/FS-926(E) – Ultra Low Set Points

These two series of precision-calibrated switches provides reliable and consistent performance; repeatability is within 1%. FS-925 and FS-926 units are factory preset for actuation at specified flow rates., These switches provide accurate detection of excessive or insufficient flow rates in such applications as: protecting against loss of fluid flow in hydraulic systems, assuring proper coolant flow in semiconductor processing equipment, monitoring high pressure lubrication systems, and ensuring proper air flow in water/waste systems., , Both the FS-925 and FS-926 use a spring-loaded piston to detect positive flow with great precision. They act upon direct fluid flow and will not show “false-positive” flow indication as can happen with sensors using indirect sensing methods such as pressure , measurement. The FS-926 incorporates an additional lap-fitted piston for very low flows;

FS-105E – Adjustable

The FS-105E model operates in any mounting position. It is equipped with a calibrated piston which is displaced by flow to magnetically actuate a sealed hermetic reed switch. When flow decreases a positive spring returns the piston to its prior position and de-actuates the reed switch. The reed switch assembly is movable to allow for customer setting of flow rate within the limits of the switch selected. The adjustment does not affect the flow path, therefore pressure drop is not influenced when changing set-points. Versions available are for Liquid flow only. Robust components allow a pressure of 250 bar, ideally suited for high pressure cleaning and lubrication systems.
