Temperature
Precision Digital offers a variety of temperature application solutions for temperature transmitters or direct temperature inputs. These include digital panel meters, explosion-proof displays, temperature scanning systems, and auto-tuning PID temperature controllers. These devices work with thermocouple, RTD, or transmitter analog inputs and include relays and 4-20 mA analog output control and alarm options. Temperature meters are available in NEMA 4X front digital panel meters and FM, CSA, ATEX, and IECEx approved explosion-proof meters for hazardous areas.

  • The Trident PD765 digital panel meter is one of the most versatile meters on the market and will satisfy a wide variety of process and temperature applications. Housed in an 1/8 DIN enclosure with a NEMA 4X front, the meter can be field programmed to accept process voltage (0-5 V, 1-5 V, etc.) and current (4-20 mA) inputs, 100 Ohm RTDs, and the four most common thermocouples. The display height on the standard Trident meter is 0.56" (14.2 mm) and on the Trident X2 the display height is an astounding 1.2" (30.5 mm). The intensity of the display can be adjusted to compensate for various lighting conditions, including direct sunlight. Programming and setup can be performed with the four front panel pushbuttons, free MeterView software, or using the copy function. Options for the PD765 include 2 relays, a 4-20 mA output, 24 V transmitter power supply, and Modbus® serial communications.

  • The SuperNova PD500 Series of PID Process & Temperature Controllers is a complete line of PID and on/off controllers. Available in popular 1/4, 1/8, and 1/16 DIN sizes, and with a shallow depth behind panel of only 2.5" (63 mm) it is easy to fit into almost any panel, product, or enclosure. Voltage, current (with external resistor), and direct temperature thermocouple and RTD inputs make it an excellent choice for any control application requiring easy to change, visible set points. This modern line of controllers shows the process variable (PV), set value (SV), and manipulated value (output level%, MV) on a striking reverse polarity LCD screen. Indicators for units (˚C, ˚F,%, or none) Auto and manual control modes can be easily changed by holding two buttons, and this is indicated on the front panel to make it easy for operators to know how to use this feature. Main control outputs can be 4-20 mA (SCR), voltage pulse (SSR), or relay outputs. A secondary relay control output is standard, which allow for one or two direction SV control (i.e., heating and cooling). Additional outputs may include two SPST alarm relays and a 4-20 mA retransmit output. Other options include a secondary 4-20 mA input to remotely control the set point, and RS-485 for Modbus communication. A mini-USB port may be used for a direct PC connection to run the SuperNova software for monitoring, programming, and data logging. This USB port is located on the rear behind the panel for PD510 1/16 DIN models, and on the front behind a rubber tab on PD520 and PD530 1/8 and 1/4 DIN models.
