The EL Series is a range of high quality,

low cost, miniature sensors which meas-

ure the temperature of inaccessible or

moving objects and materials.

They measure temperatures from -20°C to

500°C accurately and consistently, with an

outstanding response time of 200 ms.

These sensors are available as either 2-

wire units with a 4-20 mA output, or 4-

wire units with voltage or thermocouple

outputs. This choice of outputs makes the

EL series compatible with almost any indi-

cator, controller, recorder or data-logging

instrument.

The EL21 has 2:1 optics making it suitable

for most applications where the sensor

can be mounted close to the target. The

EL101 is designed for small or distant

targets and has an optical resolution of

10:1. The EL301 is designed for very small

or distant targets and has an optical

resolution of 30:1.

These compact sensors are small enough

to fit almost anywhere and their rugged

stainless steel housings make them ideal

for applications where cleanliness and

hygiene are paramount.

The EL Series Sensors are easy to install

and will operate in ambient temperatures

up to 50°C. For more hostile environ-

ments or difficult mounting conditions a

wide range of accessories is available.
