Pressure Difference Indicator (NSN 6685-33-203-0363)
H8307 pressure difference indicator is an alert and monitoring equipment for use in controlled areas where there is a pressure difference with the external environment in order to avoid the entrance or exit of any kind of contamination, as for example in clean rooms and laboratories.
It includes a tri-colour numeric LED display (red, yellow and green), and an acoustic alarm device that can be silenced by the operator. Its display indicates the pressure difference between its two input ports, with 0.1mb resolution. Two alam levels can be defined (alert and alarm).
It includes RS-232 and RS-485 serial ports, so pressure difference and alarm status can be remotely monitored throug a NMEA-0183 communication protocol.
