Battery powered temperature indicator	Stator temperatures on a blower
Steam boiler temperature panel	Temperature transmitters with digital displays
Temperature controllers	Annunciator for temperature switches

Overview

Precision Digital offers a wide variety of meters, indicators, controllers, and transmitters to satisfy just about any temperature application. Our Trident line of digital panel meters can be set up in the field for thermocouple or RTD inputs. Our Nova line of PID temperature controllers are high accuracy, full-featured controllers available in ramp & soak, programmable, and limit controller configurations. One particularly useful feature of the Fluidwell F-Series temperature indicators is that they can be battery powered. All of these products can be equipped with a 4-20 mA output; resulting in a temperature transmitter.

Bearing temperature monitoring

PD118 Minimux

PD750 Temperature indicator

In this application, five RTDs are being switched by the PD118 Minimux to a PD750 temperature meter with two relays. Currently, the Minimux is switching Stator #2 RTD and it is being displayed (105.0°C) on the PD750. The Minimux is also indicating that Bearing #2 is in alarm and this has resulted in an internal horn sounding and an internal relay tripping an external horn.

PD118 scans up to 8 inputs
Automatically switches them to PD740-3-14
PD750-3-14 checks for alarm condition
PD118 indicates alarm condition

Products: PD118, PD750, PD765

Battery powered temperature indicator

RTD input Rugged field enclosures (aluminum or plastic) Displays temperature & °C, °F, or °K units Up to 1" high digits Backlighting Relays and 4-20 mA output options	F040 F-Series Temperature Indicator
In addition to battery power, Fluidwell temperature meters can also be powered from AC, DC, or loop power. Products: F040, F043, F143

Local Temperature Display & Remote PC Monitoring
Say you have an application where you want to display the temperature in 6 different ovens right on the shop floor and also display the data and collect it on your computer back in your office. You can do this with Precision Digital's Trident meter and MeterView® software. We can also provide the enclosure and the engraved labels so you have everything you need! MeterView software even allows you to remotely acknowledge relays.	Up to 100 temperature inputs Remote PC Display Data Acquisition Acknowledge relays remotely Save data to a file

Wax Reclaim Temperature Monitoring

Trident Meters Display RTD Input Enclosure with Custom Engraved Labels 2 Relays for High & Low Alarms NEMA 4X Front
In this application, the customer is using three Trident meters mounted in a steel box to measure wax reclaim temperatures in a foundry. Products: PD765, Trident Enclosures

Stator Temperatures on a Blower in Wastewater Treatment Plant

The customer is using four Precision Digital model PD750-3-14 & five PD751-3-14 Temperature Meters to measure stator temperatures on a blower in their waste water treatment facility.

Products: PD750, PD765

Temperature transmitters with digital displays

Adding a 4-20 mA output option to a Precision Digital meter converts a temperature indicator into a temperature transmitter with a digital display.

RTD or TC Input 4-20 mA output AC or DC Power 1/8 DIN Panel cutout PDA2801 NEMA 4X Enclosure Option	Products: PD765, PD2801

Annunciator For Temperature Switch Monitoring

The Vigilante^® II annunciators are compact, panel-space saving, easy to use annunciators available in models to handle either four or eight temperature switches. Each switch can have its own custom message, such as "High Temp Oven One", on the Vigilante. When a temperature switch trips, the LED for that input flashes, a horn sounds and a relay transfers. The Vigilante annunciator can even indicate which switch tripped first.

Monitors four or eight temperature switches
First-out indication for troubleshooting
Powers the temperature switch
Free custom message labels
Built-in horn
Two Form C 2 A relays
Shallow Depth 1/8 DIN Case
