Precision Digital - Digital Panel Meters and Explosion-Proof Instrumentation


Digital Panel Meters By Application

Application - 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.

Application - Pressure

Precision Digital offers a wide range of digital panel meters and explosion-proof displays for use in pressure applications. Most of our meters include square root extraction and multi-point linearization signal conditioning features for non-linear pressure transmitter signals. This allows them to be used in even the most complex pressure monitoring systems. Pressure meters are available in NEMA 4X front digital panel meters and FM, CSA, ATEX, and IECEx approved explosion-proof meters for hazardous areas.

Application - Speed

Precision Digital's high precision digital panel meters are designed to measure a wide range of process and electrical variables, including speed/velocity. Signals are accepted from pulse, open collector, NPN, PNP, TTL, switch contact, sine wave (coil), and square wave inputs. Velocity transmitters, such as tachometers and counters, provide pulse outputs that can be read and scaled by these devices to read in engineering units on the display. All meters feature dual-line, 5- and 6-digit displays that are easily read in sunlight and from wide angles and are available in NEMA 4X front digital panel meters and FM, CSA, ATEX, and IECEx approved explosion-proof meters for hazardous areas.

Application - Weight

Digital load cell meters are high precision instruments designed to measure weight, mass, force, or deflection when connected to a load cell. Load cell inputs include 0-30 mV, 0-200 mV, ±15 mV, and ±100 mV. With a max current of 350 mA at 10 V, they can support up to twelve (12) 350 O load cells (minimum load resistance of 28 O), making them ideal for multipoint weight measurement applications. Each meter includes a dual-scale feature that allows measurements to be displayed in two different units. Alternately, the second line can show a custom tag. Load cell meters are available in NEMA 4X front digital panel meters and FM, CSA, ATEX, and IECEx approved explosion-proof meters for hazardous areas. The explosion-proof models include SafeTouch® through-glass buttons for access to zero, tare, and other functions without the need to remove the enclosure cover.

Application - Process

Process meters are high precision instruments designed to measure, display, alarm, and control a wide range of process variables, such as 4-20 mA and 0-10 V analog inputs. Precision Digital’s process meters are available with relays, analog and open collector outputs, 24 V transmitter power supply, programmable function keys and advanced signal input conditioning, all of which greatly increase their functionality and utility. Many of these meters include sunlight-readable, dual-line LED displays, wide angle viewing, increased power efficiency, and digital serial communications. Process meters are available in NEMA 4X front digital panel meters as well as FM, CSA, ATEX, and IECEx approved explosion-proof and intrinsically safe meters for hazardous areas.

Application - Hazardous Area

Precision Digital manufactures a wide range of rugged meters and controllers designed for quick and easy display of a variety of process signals in harsh or hazardous areas. These signals include 4-20 mA, 0-10 V, strain gauge, pulse, thermocouple and RTD. Our hazardous-area instruments are approved by FM, CSA, ATEX, and IECEx as explosion-proof, intrinsically safe, and nonincendive. Many of our explosion-proof models feature SafeTouch® through-glass buttons which ensure safe operation without the need to remove the cover. Intrinsically safe, loop-powered instruments derive their operating power from the 4-20 mA current loop with a relatively low voltage drop, preventing the need to run additional, costly power lines into the hazardous area.

Application - Wireless Bridge

Precision Digital’s PDW wireless products give you a simple, straightforward way to get analog, discrete, or Modbus® signals from where you have them to where you need them. Our wireless solutions range in complexity from simple point-to-point for wire replacement, to large-scale point-to-multipoint for connecting up to 32 individual field locations to a central base station. Wireless installations may be expanded or improved using an array of base station modules, additional wireless field units, and repeater units. The wireless survey tool kit can provide you with an accurate representation of wireless signal strength throughout your facility before you perform the installation.
