LARGE DIGITAL LED TEMPERATURE DISPLAYS

GENERAL OVERVIEW

These Large Digital LED Temperature Displays are ideal for all Industrial and Commercial applications for displaying Temperature across the range of  – 199 ~ 1600 °C / – 326 ~ 2912 °F

The series of Large Digit Temperature Displays will accept Thermocouple or PT100 ( RTD ) input,  to display numerically Temperature from a remote process in Large Digit format to give a clear indication of Temperature from a distance.

INDUSTRIAL and COMMERCIAL LARGE DIGITAL LED TEMPERATURE DISPLAYS 

Industrial 

These LED displays are more versatile in range and offer a wide choice of DIGIT HEIGHT and accept a wider range of INPUT SENSORS,  for most industrial application / processes. 

They are available from ranges – 200 to + 1600 °C / – 326 to + 2912 °F,   with appropriate Input Sensor.  LED Digit Height from 2.3” ( 58mm ) to 18” ( 457mm ),   with retransmission output option and Alarm output option.

Commercial

This range is aimed at the commercial market for

  • Large Walk in Refrigerators
  • Large Walk in Freezers

Commercial Displays Red, Amber, Blue, Green, White, Yellow

INDUSTRIAL LARGE DIGIT LED TEMPERATURE DISPLAYS

These displays are extremely robust for most harsh industrial applications when used with the appropriate IP or NEMA rating cases.  They can be used Indoors or Outdoors. 

They accept major Thermocouple Inputs,   J, K, T, R and 2 or 3 wire PT100 ( RTD ).   They can be Wall Mounted,  Suspension Mounted or Panel Mounted ( 2.3”, 4.0” only ). 

Retransmission Output Options

  • 0-10V, 4-20mA
  • RS-232, RS-485
  • Modbus and ASCII

Alarm Output Options

  • HI or LO 3A SPCO
  • HI & LO 3A SPCO ( All alarms are fully adjustable digitally )

COMMERCIAL LARGE DIGIT LED TEMPERATURE DISPLAYS 

These displays are aimed at the less harsh environment applications and more suited to the Chilled Food Industry and Air Temperature comfort for Offices and Factory areas

They are however suitable for INDOOR and OUTDOOR applications and have as standard IP66 / NEMA 4X rated enclosures.  They are purely for Wall Mounting,  with rear brackets supplied.

They are also supplied with their own inbuilt Temperature Sensor and will very accurately display Temperature across the range – 50.0 to + 99.9 °C / -58.9 to + 211.8 °F.

A UNIQUE ALARM OUTPUT FEATURE is also available on these Large LED displays,  programmable within the software for DAILY REAL TIME OUTPUT at different times of each day or a planned general weekly function by days.

DUAL LINE ( Multiline ) LARGE DIGIT LED TEMPERATURE DISPLAYS

Both the INDUSTRIAL and COMMERCIAL range of Large Digit LED Temperature Displays can be supplied as Dual Line or Multiline digit displays.

One such popular example of a Dual Line display is the display both

HUMIDITY   RH %
TEMPERATURE   °C / °F

This can be done with a dual 4~20mA input sensor ( see sensor section ) with the sensor probe protruding from the bottom of the case,  or an independent PT100 and a 4~20mA input.

Multiline Temperature displays have independent input sensors for each line,   Thermocouple or PT100 ( RTD ) depending on the Temperature ranges to be displayed.

MOUNTING OPTIONS of LARGE DIGITAL DISPLAYS

There are three mounting options –

Wall ( With Brackets ) and Wall ( Flush )
Flush Panel
Suspension

LED DISPLAY WALL MOUNTING

Industrial ( Bracket Mounting ) 

Wall mounting cases up to 6” high digits are supplied with side brackets that can rotate in their mounting to enable the display to be ‘ TILTED ‘.    8” high digit displays and above are normally supplied with four welded corner brackets for direct fixing to a wall.   The reason for the difference is purely weight.   If an 8” high digits displays only has 2 or 3 digits and single line,   it too can have side adjusting brackets.  12” and above are always with fixed.
