Gems Sensors offer a wide variety of flow and level sensors for different types of liquids. Single point and multipoint level sensors are available in different sizes and are designed for different types of mounting. Gems Sensors can be made of different materials depending on the intended conditions of use, and also have a different principle of operation, however, all of them have repeatedly proven their reliability and accuracy of transmitted data in various operating conditions.
Gems Sensors electromechanical solenoid valves provide efficient automatic control of the flow of liquids or gases, including air, water and steam. They are widely used in medical equipment, food processing, industry, including the automotive industry, as well as in systems for the transportation of liquids, oils and gases, analytical equipment, in clinical chemistry, heating, ventilation and air conditioning systems, in the production of semiconductors, and also for controlling large pneumatic valves.
This Gems Sensors product category includes signal and solid state relays as well as power relays. The SAFE-PAK series includes intrinsically safe programmable relays that can be either normally open or normally closed in start position, and are also available with a latch-type output. These safety switches are ideal for use with switches and sensors for flow, pressure and level monitoring. Gems Sensors intrinsically safe power relays enhance the load tolerance of the sensors without the need for costly explosion-proof enclosures.
The DF series level regulators are designed for independent control of liquid level in two parameters. Regulators can be equipped with a reset button after power off or deactivation. These level controls are ideal for use in boilers, food processing equipment, and chemical handling systems. Gems Sensors level controllers have long-term reliability, comply with the CSD1 standard and are also available in a compact design. Series 17 level regulators are approved for use in Class I and II, Division 1, Groups A-G hazardous atmospheres and are not capable of igniting flammable materials.
Control and measuring equipment
The ultra-compact Gems Sensors have been specifically designed to operate reliably in purified drinking water systems. They are made from Noryl® with the addition of other FDA and NSF compliant materials. The springs and stop are made of stainless steel. These high quality switches are competitively priced and can be used to monitor filter and UV lamp replacement times. The switches can operate at temperatures up to and including 100 ° C.
Gems Sensors 19MR Series actuators are ideal for applications where a variety of fluids need to be pumped or bumped out. There is no need for starters with these drives as they can directly drive motors up to 1 horsepower at 120 volts AC or up to 2 horsepower at 240 volts AC. The actuator is capable of operating over a temperature range of -40 ° C to 65 ° C. These drives are non-intrinsically safe and comply with UL508 for general purpose drives.
Engine speed controllers
DC motor speed controllers are designed for applications where only direct current is available. These controllers can be used as differential control elements or as one-time signaling contactors. With their long lifespan, easy connectivity and a choice of 12 or 24 volts DC, Gems Sensors engine speed controllers can be used with confidence in any situation.
Protective devices and guards
Among the protective devices manufactured by Gems Sensors, IS Zener barriers and IS relays are especially popular. For most non-voltage generating devices located in hazardous areas, a single negative-grounded IS barrier is sufficient. For generating devices, two such barriers must be used. Gems Sensors 54800 series dual channel barriers are suitable for such cases. Intrinsically safe barriers in compact design are also available.
Gems Sensors offers a wide range of RFO RotorFlow electronic flow sensor accessories, including large and standard electronic totalizers, and optional power supply modules that supply DC current to both the totalizers and the sensors themselves. The optional power supply module is mounted on the rear panel of the compact totalizer. The large totalizers are equipped with standard relay outputs and can independently supply power to the sensors (DC).
