Both M6 and M7 indicators have two outlines optional: square and round shapes. The square indicator can be connected to the pressure transmitter with a 4mA~20mA DC output signal and Hirschmann plug directly; and for the round indicator, its housing rim has many installation slots for user users’ applications, for example, using in 2088 housing.
