Level

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 MINIMUX® II PD138 is a microprocessor-based, eight-channel analog input scanner/multiplexer and annunciator that provides low-cost automatic switching for multi-point display and alarm systems. It can automatically switch up to eight inputs to another device such as a digital panel meter, controller, or PLC. Signal switching is done via reed relays making the PD138 ideal for switching thermocouples, RTDs, control loops, and AC/DC signals. They feature rugged NEMA 4X/IP65 fronts and a wide operating temperature range. They can be programmed for many common ISA alarm sequences including first out indication and they provide alarm signaling through front panel LEDs and a build in 85 dB horn. Custom printed message labels can be included with your order at no additional charge.

    Why you should buy:
    • Scans Temperature and Analog Inputs
    • Channel Alarms
    • NEMA 4X/IP65 Front
  • The PD650 is a large display, analog input process meter with flow rate/totalizer and batch control capabilities housed in a rugged, die-cast aluminum, NEMA 4X enclosure. It accepts the common process signals such as 4-20 mA, 0-5 VDC, 1-5 VDC and 0-10 VDC and displays these signals in engineering units on a 2.3" (58.42 mm) large, high efficiency, 4 1/2 digit LED display. The 115/230 VAC models also provide two isolated 24 V power supplies to drive both the input and output loops. Options include up to 4 relays for alarm or batch control and an isolated 4-20 mA transmitter output.

  • The PD655 is a large display, analog input process meter with flow rate/totalizer and batch control capabilities housed in a rugged, impact-resistant, glass-filled, polycarbonate NEMA 4X enclosure. Each accepts the common process signals such as 4-20 mA, 0-5 VDC, 1-5 VDC and 0-10 VDC and displays these signals in engineering units on a large, high efficiency, 4 1/2 digit LED display. The meter also provide two isolated 24 V power supplies to drive both the input and output loops. Options include up to 4 relays for alarm or batch control and an isolated 4-20 mA transmitter output.
