Moving objects need only appear in the measuring field of the new Optris Ctfast sensor for only 4ms for the unit to be able to detect temperatures ranging from -40 to +600C.
Moving objects need only appear in the measuring field of the new Optris Ctfast sensor for only 4ms for the unit to be able to detect temperatures ranging from -40 to +600C.
This opens up a wide range of possible applications for the new sensor.
For example, the measurement of the temperature of hot wheel bearings in moving trains.
Measuring the temperature of the wheels of moving vehicles can now be temperature controlled at high speed safely and accurately.
Similarly, measuring the temperature of objects in "freefall" can now be monitored for overheating and temperature difference.
The new device can also be used in safety at work applications such as the temperature control of bulk goods on coal dumps, where glowing remains could cause a fire.
The sensor also comes into its own when monitoring the temperature of small components (2mm) moving down conveyor lines.
The Optris Ctfast is one of the smallest infra-red sensors in the world with exposure times between 3ms (50% signal) and 9ms (90% signal).
It has a fast analogue output with intelligent real time data processing and an instant digital output with a response time of 4ms.
The sensor is easy to assemble in multiple arrays for line scanning of small, fast moving objects (hot spot detection) using an RS485 bus connection.
The unit is also rugged up to 180C ambient temperature without any cooling.
The sensor unit is compact.
The sensing head measures just 28mm in length with a diameter of 14mm.
The control and electronics box measures just 120 x 7m x 30mm, making the complete unit easy to integrate into a company's production line.
The sensor is easy to set up and can be controlled remotely.
There is automatic data logging for analysis and documentation.
A graphics display shows fast temperature trends and users can programme analogue and digital inputs to take external emissivity and ambient temperature into account.
Alarm output signals can be programmed and digital remote communication is possible for up to 32 sensors in a single network.
The electronics is housed in a stainless steel body and accessories are available for cooling and air purging.
The complete range of Optris products includes infra-red thermometers, infra-red sensors, infra-red calibration sources, portable thermometers and infra-red cameras, used in a variety of applications including process control and automation, temperature monitoring for OEMs, heat measurement, thermal imaging and measurement of process temperature.
Optris products are available in the UK through Micro-Epsilon (UK).
