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 ProtEX-MAX PD8-6080 Super Snooper Modbus® scanner offers all the functionality of the ProVu PD6080 as a fully FM, CSA, ATEX, and IECEx approved explosion-proof product. It is a multi-purpose display and controller capable of scanning up to 16 process variables and includes dual analog process inputs. The scanner can be programmed as a Modbus RTU master, slave, or snooper. It is the ideal display for Modbus multivariable transmitters or for existing Modbus networks with transmitters in need of a conveniently located display in a hazardous area. As a master, the PD8-6080 can read up to 16 Modbus registers on up to 16 Modbus devices and automatically alternate each of these process variables (PVs) on the dual-line display along with a unit and tag for each. In snooper mode, the scanner can read any Modbus variables being polled by a master, which allows you to easily add a display into an existing Modbus network. Powerful math functions may be applied to the analog or Modbus inputs, such as addition, difference, average, and ratio. The PD8-6080 includes a 24 VDC power supply to drive the transmitter and can be equipped with four internal relays and two 4-20 mA outputs. It can be programmed and operated without opening the housing by using the built-in SafeTouch® through-glass buttons.

  • The PD662 NEMA 4X, CSA Certified loop-powered meter is perfect
    for applications where a simple, inexpensive display is required
    and AC power is not available. The PD662 derives all its power
    from the 4-20 mA loop, including its optional backlight feature. It
    can be easily scaled in the field using four push buttons; with or
    without applying an actual calibration signal. The PD662’s display
    will read up to 2999; we call this 3½+ digits! The PD662 is housed
    in a rugged NEMA 4X enclosure and is provided with one ½" NPT
    pipe conduit hole.

  • The ProtEX-MAX PD8-6081 Super Snooper feet & inches Modbus® scanner offers all the functionality of the ProVu PD6081 as a fully FM, CSA, ATEX, and IECEx approved explosion-proof product. It displays level information on a specially designed feet & inches display, instead of the usual decimal format. It is the ideal display for hazardous areas with Modbus level or multivariable transmitters and is capable of scanning up to 16 process variables. Its unique feet & inches upper LED display can indicate up to 99 feet, 11 and 15/16 inches. The 6-digit lower display can indicate units, tags, or other variables such as volume, temperature, or density. The PD8-6081 also has dual analog inputs, for integrating traditional 4-20 mA or voltage inputs in the display scanning. The scanner can be setup as a Modbus master, slave, or snooper. Various math functions may be applied to the analog or Modbus inputs, such as addition, difference, average, and ratio. The PD8-6081 includes a 24 VDC power supply to drive the transmitter and can be equipped with four internal relays and two 4-20 mA outputs. It can be programmed and operated without opening the housing by using the built-in SafeTouch® through-glass buttons.

  • 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.

  • The ProVu PD6088 Super Snooper Modbus® scanner displays up to 16 Modbus process variables (PVs) on the bus using its RS-485 serial input. The PD6088 can function as a Modbus master, slave, or snooper. As a Modbus master, the PD6088 can poll multiple Modbus devices for up to 16 Modbus process variables. As a slave, a Modbus master can write up to 16 PVs to the scanner for display. In snooper mode, it can sit anywhere on the Modbus network and display up to 16 PVs being polled on the bus. When connecting a scanner in snooper mode, no other Modbus devices on the network need to be reconfigured, making it easy to add additional local or remote displays to a Modbus network. Like all ProVu meters, the PD6088 includes UL / C-UL listing and CE marking, a NEMA 4X front, and AC or DC power options. Various math functions may be applied to the analog or Modbus inputs, such as addition, difference, average, and ratio.
