Process Meters
Process meters cover a wide range of display, monitoring, and control devices all of which accept process inputs: direct current or voltage inputs from transmitters. This makes them very versatile for applications across the range of flow, level, pressure, and temperature; anywhere a measurement device outputs a process signal and a local display or monitor is necessary. |

Temperature Meters
Precision Digital temperature meters accept a direct temperature input from a thermocouple or RTD. Many also accept process inputs from temperature transmitters. Our Trident line of digital panel meters can be set up in the field for thermocouple or RTD inputs. All of these products can be equipped with a 4-20 mA output; resulting in a temperature transmitter. Relay alarm outputs are also available. |

Level Meters
Level is one of the most common applications for Precision Digital products and we offer a wide variety of products to satisfy just about any level display and control application you might have. Our products can power the level transmitter, be scaled in any engineering unit and linearized for non-linear shaped tanks, control pumps and valves with up to four relays, connect to a computer, and output a 4-20 mA signal. |

Pressure Meters
Precision Digital offers digital pressure gauges that will take a direct pressure input as well as digital meters that will accept the voltage or current output from a pressure transducer or transmitter. The digital pressure gauges are available in Precision Test, Industrial and General Purpose versions. The digital meters will provide the power to drive the transmitter or transducer and can be field calibrated for display in engineering units. |

Flow Rate Meters
Flow rate meters are designed to display the rate of flow of any material. They accept a process input from a flow meter, and scale this value to an engineering value to be displayed. Often these meters have relays or analog outputs to monitor, alert, or control the rate of flow, as well as power supplies to power the flow meter being used. Because they scale the process signal, the absolute rate can be as small or large as the number of display digits will allow; from liters per day to gallons per second. |

Strain Gauge Meters
Strain gauge meters are used to measure weight, mass, force, or deflection when directly connected to a strain gauge. All common strain gauge inputs can be used including 0-30 mV, 0-200 mV, ± 15 mV and ± 100 mV These units provide the 5, 10, or 24 volt excitation for the strain gauge and scale the reading to display engineering units. Analog and relay outputs are also available for process monitoring and control. |

Auto-Tune PID Controllers
Auto-tuning PID controllers offer the accuracy of PID control without any of the complicated setup and tuning required that is often a part of PID control systems. The PD540 Series provides auto-tuning PID set point control. The PD550 Series provides similar PID control but using ramp & soak set point programs. Additional outputs, Modbus serial communication, and digital inputs allow them to greatly expand on their basic functionality. |

Alarm Annunciators
Alarm annunciators are panel mounted devices that monitor discrete inputs and offer visual indication and an audible alarm if an input alarm state is detected. Precision Digital offers 4 and 8 channel annunciators that are NEMA 4X, sunlight readable, and come with custom printed adhesive message labels for your specific application. |
 |
Scanners
A scanner allows one other meter to display multiple process or temperature inputs. The scanner cycles through each input, with a visual display of what input is currently selected, and displays it on the meter attached to the scanner. This is a simple low-cost alternative for multiple meter solutions |
 |
Modbus Products
Precision Digital offers Modbus serial input displays and Modbus serial communication data sniffers. These devices integrate into a Modbus network and can serve as masters, slaves, or passive data sniffers (aka: Snooper Mode) to introduce meters into the network. These displays can also retransmit the Modbus data as a 4-20 mA signal, or have relay alarm outputs based on the data. |

Calibrators
The accuracy of instrumentation has improved greatly over the decade. A true calibration requires that the calibration standard be approximately four times as accurate as the unit being calibrated. Fortunately, precision calibrators have advanced with this change, and surprisingly prices for the calibrators have come down in many cases. So much so that a new look at the cost of owning vs. using outside calibration services may be wise. Our multi-function calibrator calibrates a wide variety of instrumentation. It can also simulate temperature (RTD & TC) signals, or mA and voltage signals for calibration and/or system testing. It can also test/qualify temperature sensors directly. |
