Further product information
Combined with a liquid level sensor (e.g. T-200F, EF2 or EFV2) and a leak detector (e.g. T-200L, ELH or EP) the OAA-300 can be used as a local monitoring device of a tank. OAA-300 records the limit-value signals of the connected level sensor / leak detector and releases an acoustic signal and an optical signal (acknowledgeable). The device is provided with an opencircuit and a short-line fault monitoring. Each input has a floating changeover contact (having the same working principle as a “lamp” contact) as an additional output for controlling actuators, for example. It is also possible to connect an external acousto-optical signalling device to the alarm indicator. All output contacts are operated in closed-circuit working.
- Compact design for local installation
- protection class according to EN 60529: IP 65
- Available with 1 to 4 channels
- Internal acoustic signal and optic signal Outputs for controlling external signal lamp or alarm horn
- Additional separate outputs for controlling shutoff valves , alarm relaying to the control room etc.
- Integrated monitoring device (with optic / acoustic alarm indicator)
- Alarm indicator with more than 4 channels on request
