Thermosensor offers easy noncontact
measurement
A novel infra-red thermosensor provides an accurate, highly stable and cost-effective way to measure the temperature of objects.
A new infra-red thermosensor provides an accurate, highly stable and cost-effective way to measure the temperature of objects The ES1B works by producing an output signal (in millivolts) that is proportional to the temperature of the object, just like a standard thermocouple

Sound assessment diagnoses machine faults
Signarc is a novel quality control service with technology to detect product quality by assessing and diagnosing sounds and vibrations emanating from motors, drives or other moving parts.
Unlike standard thermocouples however, the ES1B has no contact with the measurement object.
This makes it particularly suitable for the food manufacturing industry: as it does not come into contact with the food it is very hygienic, and it can continuously monitor the temperature of food items to ensure safe, high-quality products.
The thermosensor's silicon-based cable and IP65 protection means it is resistant to dust and water, making it ideal for use in applications as diverse as baking, packaging, sealing and laminating.

Sensor series provides fast, accurate measurement
A new series of inductive displacement sensors claims new standards in fast, precise measurement sensing.
What also makes the ES1B so suitable for these applications is that in each case the object to be measured is moving, but because the sensor is contact-less it is not affected by wear and tear.
In the paper, printing and textile production processes, the ES1B can be used to measure the location of the product's dry-out point.
An accurate dry-out measurement point helps to reduce energy costs by saving on heating processes.
In the packaging sealing industry, the ES1B can measure the temperature at the point where the actual sealing takes place to ensure consistent quality and minimise production failures.
The ES1B behaves just like a standard K type thermocouple, which enables it to operate with any temperature controller or alarm unit.
Four models are available, each being calibrated for a specific temperature range (10-70, 60-120, 115-165 and 140-260C) to cover most application requirements.
Each thermosensor is designed to give reproducibility to within 1% of its range.
Because it is an active sensor, the ES1B is more sensitive than passive IR sensors, and so it can be mounted up to 40% further away from the measured object to generate the same output.
Once the ES1B and instrument combination is calibrated, the reproducible signal is always available and provides not only stable, real-time temperature measurement but also reduces downtime of the machine.
This is what makes the ES1B very cost effective.
The ES1B is also very versatile.
It can be used with proximity sensors (such as Omron's E2A) to indicate when to measure the temperature of moving objects on an assembly line.
It can be used with panel indicators (like Omron's K3MA) to identify an alarm condition.
It can also be used with temperature controllers (for example Omron's E5CN) to control the temperature of a moving object.
