Temperature indicators

General Information

Introduction

The product group "Temperature Indicators" offers several solutions from a basic temperature indicator up to a powerful temperature monitor with signal transmission, high / low temperature monitoring, four alarm outputs as well as full Modbus communication.

The functionality of this product group is based on two product series:

  • F-Series: this product range is supplied in a robust IP67 (NEMA Type4X) field mount enclosure and suitable for safe and hazardous area applications. The F-Series have been certified according ATEX and IECEx by DEKRA and according CSA C-US and FM for use in Intrinsically Safe applications. The F-Series is resistant to harsh weather conditions (rain, snow, salty atmospheres, temperatures between -40°C/-40°F and +80°C/+178°F) without use of expensive protective cabinets.
  • D-Series: these products are supplied in a unique DIN panel mount enclosure and is only suitable for safe area applications. The robust IP66, IP67 (NEMA Type4X) front enclosure is made of die cast aluminum and is unequaled by any panel mounted indicator in the market: The D-Series is able to withstand total immersion and even powerful water jets! Click here to see an impressive waterproof demonstration of the D-Series.

Wireless data re-transmission and remote temperature monitoring is offered with the ProcessMonitor products and services .

Easy menu structure

The F-Series and D-Series are outstanding user-friendly. No configuration with complicated hardware changes or actions! Instead, each product offers the same simple, logical menu-driven structure. Each setting is clearly indicated with an alphanumerical description, without confusing abbreviations and difficult codes. Once familiar with a Fluidwell product, you can program ALL models in ALL series without need for a manual: Know one, know them all!

Both series have so many different combination possibilities for sensor in- and outputs, power and sensor supplies, communication and external inputs, that Fluidwell is able to produce no less than 200,000 different versions! With this variety of combinations, there is always a D- or F-Series that meets your technical requirements. For an explanation of the various options, please read the section detailing the F-Series or the D-Series products.

Operator information More >>

The following features are available on all temperature indicator models. Further product specific features can be found in the products datasheet.

  • Clear operator information is a key feature of these products. Essential information is displayed as clear text (e.g. "Low temperature") and not as mysterious abbreviations.
  • The dedicated display shows two lines of information at the same time, so the actual temperature is displayed simultaneously with the measuring unit or alarm message.
  • The actual temperature is displayed with six 17mm (0.67") high digits.
  • The measuring unit is displayed with 8mm (0.31") digits. The following units can be selected through software: °C, °F, K or no unit.

Signal input type More >>

For the temperature indicators, three basic signal input types are available:

  • Analog signal: (0)4 – 20mA or 4 – 20mA input loop powered version. The input signal can be tuned within this range (e.g. from 4.0mA to 10.0mA). To avoid signal processing at minimum signal, a low cut-off filter is available.
  • Analog signal: 0 – 10V DC. The input signal can be tuned within this range (e.g. from 2.0 to 5.0V DC). A low cut-off filter is available here too, to avoid signal processing at minimum signal.
  • PT100: 2, 3 or 4 wire PRTD sensor.

Further, a digital filter can be set to a desired value to stabilize the temperature measurement reading. The offset function allows the indicator to be operational within any desired range (e.g. from -80°F to 640°F).

Data protection More >>

All settings are stored in EEPROM memory ensuring that information is not lost in the event of power failure or battery exchange. The configuration menu and alarm values can be password protected to prevent unauthorized access.
