The Precision Digital ProtEX+ series is designed for hazardous areas, featuring indicators that are loop-powered and certified as explosion-proof, dust-ignition proof, and flame-proof. These reliable meters can display any 4-20 mA signal, featuring a dual-line display. The top display shows the process variable in a clear 5-character format, while the bottom display can show units of measure or a custom tag in 8 characters. For models that measure level, the top display shows feet and inches, and the bottom can display a tag or custom message. Additionally, there is a 20-segment bargraph for easy visual reference.
These meters are certified by CSA for safe operation in hazardous environments, and they also hold ATEX and IECEx certifications for intrinsic safety. They can function in extreme temperatures, operating as low as -40°C, although the display will not work in temperatures below -55°C.
With four CapTouch buttons, you can operate the meter without removing the cover. These buttons can be set to normal or delayed modes, or even disabled for added security. Each model includes two open collector outputs and a digital input. Some versions also offer two solid-state relays and isolated 4-20 mA analog output options. The open collector outputs serve as alarm indicators, while the digital input can be used to acknowledge relays, start or stop a timer, and more. The relays can be programmed for various functions, including alarm indication, on/off control, or pump alternation.
For easy programming and setup, Precision Digital provides free PC-based software called MeterView XL. This software connects to the meter via a micro USB cable, making programming straightforward. It also allows you to save configuration files and powers the meter during the setup process.
