Zero governors are used to supply gases at atmospheric pressure to the mixing chambers. These are mainly used for furnaces in glass industry. They are very sensitive and precisely maintain the required outlet pressure.
Zero pressure roller conveyors are used for non-contact accumulation and buffering of sensitive or fragile loads. The conveyor is equipped with logical sensors and can therefore also be independently operated from an overall material flow control system e.g. stand-alone mode for manually actuated release of queues.
Zero Speed Switch is used to detect the absence or presence of motion of rotating, reciprocating or conveying equipment. It consists of a circuit card and magnet assembly potted in the probe body. It is powered from the line voltage and provides a set of dry relay contacts for indication of motion. The probe must be aimed at a ferromagnetic material or target on the equipment in order to sense motion. It is sensitive to lateral disturbances to its magnetic field. These devices are shaft or pulse driven and can indicate or control the rotary motion of the equipment they are attached to.
