The Precision Digital PD6620 is a dependable and adaptable instrument designed for monitoring flow rates and totals in various industrial settings. Its intrinsically safe and non-incendive design allows for easy installation in any location, providing detailed data from a 4-20 mA signal.
One of the key highlights of the PD6620 is its dual display capability. The top line features a 5-digit alphanumeric display that typically shows the flow rate, while the bottom line has an 8-digit alphanumeric display for the total or grand total. Both lines use clear 14-segment characters, making it easy to read tags, units, or alarm messages. Additionally, the PD6624/6 models come with a 20-segment bar graph that visually indicates the percentage along with a numeric value.
Installing the PD6620 is straightforward since it draws power from the 4-20 mA loop, eliminating the need for an external power source. It has a minimal voltage drop of just 1.5 V (4.7 V with backlight), ensuring it does not significantly impact the loop. The device features a robust NEMA 4X, IP65 front panel, making it suitable for a wide range of environments, with an operating temperature range of -40 to 158°F (-40 to 70°C). The conformally coated PCBs enhance durability, and the backlit LCD ensures readability in both bright and dim conditions. Furthermore, the PD6620 is designed to be intrinsically safe and non-incendive, making it ideal for hazardous locations.
For easy programming and setup, users can connect the meter to a PC using a micro USB cable and the included software. Alternatively, programming and operation can be done directly on the device using the four front panel buttons, three of which can be customized as function keys. The PD6620 also features a digital input, which is useful for remotely resetting the total or controlling timer and batch start/stop functions.
This instrument offers versatile output options, including two open collector outputs, two solid-state relays, and a 4-20 mA analog output. The open collector outputs can be utilized for alarm notifications or to send pulses when a specific total is reached. The relays can be programmed for alarm indications, on/off control, sampling, or simple batch control, adding to the instrument’s versatility.
Discover the reliability and ease of use of the Precision Digital PD6620, equipped with advanced features and comprehensive functionality, perfect for monitoring flow rates and totals in industrial applications.
