Pyrometer cooling jacket for high temperatures

The ThermoJacket supplied by Raytek and Fluke Process Instruments allows for selected sensing heads to be used in ambient temperatures up to 315°C. The ThermoJack- et’s rugged cast aluminium housing completely encloses the sensing head and provides water or air cooling and air purging. The following pyrometer sensors are covered. - MM sensors - TJ4M ThermoJacket - Thermalert TX sensors - TJ3M ThermoJacket - Thermalert 4.0 sensors - A-TJ-T40 ThermoJacket - Endurance sensors - E-TJ1 ThermoJacket. The table below shows water/air flow requirements at different temperature levels.

The cast aluminium Thermojacket protects sensors in use in high temperature environments.

A longer range alternative to ultrasonics

The T30R from Turck Banner offers more robust detection capabilities and longer range than ultrasonic solutions in a similar package size and without the risk of crosstalk from multiple sensors mounted close together. The compact radar sensor has an IP67-rated housing making it suitable for use in challenging environments. It is resistant to ambient weather such as sunlight, wind, rain and snowwhere such conditions can be problematic. Radar waves are not affected by ambient temperature changes, providing consistent measurement from -40 to 65° C (-40 °F to +149 °F). The 15 m range and high level of performance in harsh environments make the T30R ideal for outdoor detection at loading docks, for example, and at tolls, gates and car washes. More precise than traditional 24 GHz radar Like other Banner radar sensors, the T30R features Frequency Modulated

challenging lower-dielectric materials, such as wood, rock, or organic material.

Easy setup and integration The T30R can be programmed using the intuitive configuration software (supplied free of charge), remote teach input, push buttons, or IO-Link for flexible setup and configuration. Dual discrete outputs are available for slow and stop positions and analogue and IO-Link options are available for absolute distance measurement. The T30R also features Banner’s Pulse Pro output that can connect directly to a range of Banner lights to provide direct process feedback to the operator by illuminating a light green to yellow to red, or any custom configuration. Pulse Pro requires only power and no separate controller is needed. The T30R solves various challenging applications, including, among others: - Collision avoidance of mobile equipment - Positioning of baggage handling trucks and passenger bridges at airports - Outdoor detection and measurement applications - Vehicle detection, profiling, and positioning - Level measurement applications - Car wa sh vehicle profiling.

The T30 radar sensor detects whether other sensors cannot.

Continuous Wave (FMCW) for detection of stationary and moving targets. However, the T30R offers much more precise detection of a wider variety of materials than traditional 24 GHz radar. Banner’s T30R can detect objects as close as 150 mm and can measure with linearity and repeatability at less than ±1 cm.

The T30R can detect high-dielectric targets reliably, such as metal or large amounts of water, as well as
