What is use of zero speed switch?
Zero speed switches (ZSS) also known as Speed Actuating Sensing Switches are used to detect whether a rotating shaft is turning (even at very slow speeds) in various machines, conveyors, power plants, and in industries involving the production of cement, sugar, textiles, paper, etc.
How does a zero speed sensor work?
Speed Sensors and Zero Speed Switches When the sensor or switch detects a change in speed or zero speed, a signal is sent to a control panel or an alarm to alert the operator of a malfunction. The process may be halted to prevent damage to other conveying or processing equipment.
How do speed switches work?
How do speed switches work? Speed switches contain a non-contact inductive sensor probe positioned near the rotating object. Small metal flags or magnets are mounted on a disc or pulser wrap, which generate pulses as they pass through the probe’s electromagnetic field.
What is speed switch?
A Shaft Speed Switch is a device that monitors rotating shafts that are critical to the proper operation of many types of machinery. It can be used to alarm an operator of any undesirable or critical speed condition of the monitored shaft such as rotating too fast, too slowly, or a combination of these.
What are the uses of zero speed switches?
Zero speed switches (ZSS) also known as Speed Actuating Sensing Switches are used to detect the stoppage or unacceptably slow movement of a rotating shaft. Generally its applications are in various machines, conveyors, power plants, and industries involving the production of cement, sugar, textiles, paper, etc.
Which is the best non contact safety switch?
Our Ferrogard™ 1, 2, 20 and 21 Non-contact Interlock Switches have plastic rectangular housings, making them ideal for wet environments. The magnetically actuated safety switches offer non-contact reliability together with tolerance to misalignment.
How big should the interconnecting cable be for a zero speed switch?
However, the interconnecting cable should be of minimum 0.5sq. mm. Size. ALED provided on rear side of the probe gives visual indication for sensing of the flag. In case of sensors other than Inductive type the pulses generated are to be connected as specified for the individual sensor.
What makes a non contact interlock switch non contact?
For non-contact interlocks, no physical contact (under normal conditions) takes place between the switch and actuator. Our SensaGuard™ Non-contact Interlock Switches feature the latest generation of RFID technology for coding and inductive technology for sensing.
