Current sensors in the form of current loops or current clamps are sensors through which a power cord is run. The loop and clamp is in two parts and attaches around the cable to be measured. The current passing through the cable is measured using induction to generate a value in Amps of the power being drawn by the connected load. The current sensor is connected to an base environment monitoring device which acts as central point for data collection. Monitoring software is used to analyse the data and trigger an alarm notification outside threshold settings.
AC Mains Power Failure Sensors
These AC mains power failure sensors plug onto an environmental monitoring system and detect the presence (or not) of an AC power supply (mains power or AC generator). Any change of state will lead to an automatic alarm notification sent using email, SMS text or SNMP, dependent on the base monitoring device connected to the sensor. The monitoring base units can be connected to the local internet using an IP network connection (Ethernet cable or WiFi) or installed with a GSM SIM card to allow remote access, reporting and alarm sending. Click on any of the sensors below to see more information and the related devices they can be connected to for montoring and alarms.
