Indoor Differential Pressure Transmitter – Overview

The PMD330 indoor differential pressure transmitter is used to measure the pressure drop between two points. Ideal for use in the building management, hospital or pharmaceutical industry to make sure filters are in good working order. The ergonomic design allows for the unit to display options on a backlit LCD monitor. The units come with analogue or digital Modbus RTU communications options. Ranges can be defined by a dip switch and the device can be calibrated and adjusted with software. With options of a M12 Connector or wired through a cable gland.
