Level FM (IS) Large Display Process

Level
Level is one of the most common applications for Precision Digital’s meters. Our most popular products can be used for level applications and we also have meters that are specifically intended for use in level systems. These digital panel meters and explosion-proof indicators communicate critical level information at eye-level to the operator, effectively increasing safety by eliminating the need for operators to climb the tanks. The level can also be controlled with the use of relays, open collector, or 4-20 mA analog outputs. Select products include specialized level features such as pump alternation control, unique feet & inches displays with clearly labeled units, and dual-scale level displays that show level in two units from a single transmitter signal.

  • The PD686 is an Intrinsically Safe and Nonincendive, NEMA 4X, loop-powered indicator that is easy to install and program and can be seen from considerable distance. The fact that this meter is loop-powered means that there is no need to run additional, costly power lines into a hazardous area; the meter gets all of the power it needs from the 4-20 mA loop and the PD686's 1 V drop results in a minimal burden on the loop. The meter features FM and CSA approvals as Intrinsically Safe and Nonincendive, a wide -40 to 85°C operating temperature range, and is provided with a ½" conduit hole in a location of your choice for easy installation. Calibration is a quick two-step process involving the adjustment of only two non-interacting potentiometers.
