The Dwyer Series MDPC Mini Digital Pressure Controller is a slim, gas pressure sensor small in size and light in weight. This pressure controller supports many installation methods and features a high measurement accuracy. This small controller yields excellent stability, high shock, and vibration resistance. The MDPC also provides good over-load capacity and heat resistance. It can be utilized in many industries such as high-tech electronics, general processing, food packaging, and automatic assembly. The MDPC features 6 user-selectable pressure units and a large, LED 3-color display with selectable color options that allow for easy reading. Changing units is simple, and by using the included unit stickers, the pressure unit displayed becomes very clear. The fast parameter copy function makes copying parameters to other MDPC pressure controllers effortless. The key lock mode also prevents any unnecessary changes to the parameters, which can affect the operation. Another characteristic of this multi-talented pressure controller is its ability to detect both positive and negative pressure. The MDPC is available in NPN, PNP, analog voltage, or current output control modes.
