LEVEL DETECTION SENSOR can see through metal walls

The levelprox level detection sensor is designed for use with metal storage tanks. It has the ability to detect liquid levels inside a metal-walled tank without the need for an access port. The unit is suitable for applications in breweries, dairies and other food or beverage production facilities, wastewater treatment, chemical handling, oil or lubricant storage and pharmaceutical. Using ultrasonic technology to sense through the metal tank wall is ideal for situations where intrusion into the tank is not desired, such as when the media is caustic or volatile, under high pressure, at very high temperatures and especially if the environment is sanitary. There is no direct contact with the media and it is not affected by stirring devices.

WARNING SYSTEM for optical and acoustic in-situ signalling

Rittal's Signal Pillars give users the ability to identify messages and malfunctions quickly and from a distance so that prompt, targeted action can be taken before any major damage is caused. The modular construction allows flexible configurations that simplifies stock control as there is no need to keep various pre-assembled consoles in stock. Up to five separate optical components are joined together with a bayonet connection. Electrical connection is made automatically and the last component in each case may be an acoustic alarm with continuous or pulsating tone. Materials used are polyamide and polycarbonate and the system color is black. Signal lights are available in red, green, amber, blue and transparent with steady light, flashing light or stroboscopic light intervals.

EXHAUST GAS TEMPERATURE GAUGES have increased functionality

The PYRO 2001 EGT gauge combines the convenient mounting and packaging of a conventional analog fitting into a standard 2 1/16" hole plus the simultaneous display of two Type K-EGT sensors. In low light or nighttime situations, eight high intensity backlit LEDs provide a bright and an evenly lit LCD display. The PYRO 2001 also provides a peak hold and a real time data-logging feature. These features allow the user to capture either peak readings or continuous data over a given run so that the data can be played back and reviewed in real time after the run.

GAS/LIQUID SEPARATORS remove +99% of entrained liquid from air, gas and steam systems

Wright-Austin series 30L gas/liquid separators can remove +99%  of all liquid and solid entrainment, 10 microns or larger, from air, gas and steam lines. The unit is available in eleven different configurations. There are units for both vertical and horizontal installations and with numerous inlet and outlet configurations. These separators feature a very simple, yet highly efficient design. Because there are no moving parts, maintenance is not a consideration. In operation, as steam, air or gas enters the unit it encounters curved stationary blades, creating a controlled centrifugal action. Entrained liquids and solids are forced to the outer wall and then to a drain, from which they exit.

LINEAR DISPLACEMENT SENSOR helps keep processes in line

PLCD linear sensors are used in many types of drives, machinery, automation systems and conveyors. It can be applied to rotary actuator applications. If necessary, a standard signal processing ASIC can be integrated with the sensor for AC voltage supply, internal signal processing and DC out signal. PLCD sensors operate without being mechanically connected to the driving mechanism; therefore, the sensor can be actuated through walls made from non-magnetic materials. The sensors have a measurement range of 15mm to 400mm with a sensor magnet gap range of 1 to 20mm. Environmental sealing is rated at IP67 with higher ratings available on request.
