A family of sensors for use in industrial market with dry or Volt-free output. These sensors are specifically designed to work with any monitoring system that can interface to a dry contact sensor for monitoring purposes.
Low cost and reliable, these sensors can be used in any situation, including domestic, office, warehouse and server and computer rooms.
A dry or Volt-free contact is a contact without any voltage going through it. This effectively is a switch, meaning that if a sensor has a dry contact output, the switch will close when the sensor is triggered due to the presence of what it is measuring.
Dry contact sensors do not give a value. They detect the presence of something, whether it is gas, door close, smoke, water leak etc.
These types of sensors are normally connected to products that are monitoring events and act upon them, either by sending an alert or triggering a relay for example.
Although the output of the dry contact sensor is virtually volt-free, most require a DC voltage supply to operate. This power is either taken from the monitoring system, or by connecting the sensor to a wall socket.
Power Egg is designed to detect and/or disconnect 110 to 230V AC mains voltage. The controlling and controlled circuits are electrically isolated. Low-voltage, closing contacts are used for detection indication and output control.
PowerEgg is a "pass-through mains outlet" with two IEC-320 connectors – a plug (C14) at the input, and a socket (C13) at the output.
PowerEgg combines two functions in a single device:
|first level||10 ± 3% LEL (0.50% vol)||18 ± 3% LEL (0.30% vol)||23 ± 3 % LEL (0.30% vol)|
|second level||18 ± 3% LEL (0.80% vol)||30 ± 3% LEL (0.50% vol)||40 ± 3 % LEL (0.50% vol)|
|LEL = Lower explosive limit (100%) according to IEC 60079-20-1: for methane 4.4% volume concentration for propane 1.7% vol, for iso-butane 1.3% volume concentration, calibrated in the production of iso-butane|
