Temperature and Humidity large displays

Temperature and humidity can have a big effect on product quality, ease of handling and product lifetime.

We offer a range of sensors and displays to suit your environmental monitoring needs perfectly, so that you and your team can see at a glance your exact environmental conditions.

large digital temperature display

Sensors can be local or remote, suited for industrial, laboratory and quality applications.

Digit sizes are available from 14mm up to 400mm.

refrigeration temperature display with blue digits

Large digit temperature display with red digits

Our displays are designed for washdown environments, with IP65 cases, sealed all-round, with glanded cable entries.


Atex and Ex certified large digital displays
For hazardous areas, we can also produce custom Atex large displays to suit your requirements. Ask us for details.




A typical display with 57mm high digits to show temperature and humidity. We can also supply displays with 102mm, 150mm, 200mm, 300mm and 400mm high digits.

simple temperature and humidity monitor display



Individual displays with 57mm high coloured digital displays to show temperature, humidity and barometric pressure. Sensors are shown also. We can also supply displays with 102mm, 150mm, 200mm, 300mm and 400mm high digits.

simple temperature and humidity monitor display



Individual display with 102mm high digits to show temperature and humidity using our P18-1 combined temperature and humidity sensor.

4 inch  single line temperature and humidity display






Large digit temperature display in fire service application:

This large display is portable and connects directly to a type K thermocouple, which is mounted in the fire zone. The digits are 102mm high and are ultra-bright for clear visibility outside in direct sunlight. The display can store the peak flame temperature, for later recall. It is sealed IP65 all round ...





Temperature & Humidity transmitters

Ideal for monitoring temperature and humidity in production environments. Choose either 2 x 4-20mA output or RS485 Modbus RTU output.



Datasheet
Manual for Modbus P18
Manual for analogue P18L

New - LCD display version now available
The New P18-D includes a backlit LCD display, to show Absolute Humidity, Relative Humidity, Temperature and Dewpoint.

Temperature and Humidity display with dewpoint

A sealed pushbutton area lets you select either of the 4 parameters to display.

Key points :-

1. Wide range suits most industries
2. Analogue or serial outputs
3. Choice of filters for the sensor
4. Rugged, reliable, smart.




The LEL18 transducer is for the continuous measurement and conversion of relative humidity and ambient temperature into a digital or analogue voltage or current standard signal. The transducer may be programmmed and calibrated through the RS-485 interface.

Sensor shields allow the transducer to operate in various ambient conditions, dusty, dry, corrosive etc.. The transducer is designed to be mounted on a wall.

The LEL18 transducer performs following functions:

  • calculation of selected physical quantities, (dew-point temperature, absolute humidity)
  • conversion of measured quantities into a linear output signal
  • memory of maximum and minimum values for each value
  • programming of the measurement averaging time
  • servicing of RS-485 interface in MODBUS RTU mode.

Technical Data
Basic parameters:
- relative humidity measurement (RH) 0...100% without condensation
- basic error +/- 2% for rh 10...90% +/- 3% for remaining range
- hysteresis for humidity measurement +/- 1%
- temperature measurement range (T) - 30...85oC
- temperature conversion accuracy +/- 0.5% of the range
- calculates abs. humidity (a) [g/m3] dew-point temp. (Td) [oC]
- additional errors: temp. effect +/- 25% of basic error/10oC
