Hawk, a leading global provider of level, positioning and flow measurement technology, announces the Gladiator Vibration Switch Series, a heavy-duty point level switch that ensures years of trouble-free operation. The level sensing arrangement used in the Vibration Smart Switch is suitable for a wide range of liquids and solids, including slurries and pelletized materials. The sensing element includes two prongs or vanes. When the prongs on the fork are free to vibrate they are driven to their resonant frequency by piezo ceramic elements. As the level of the material to be sensed rises, the material blocks the movement of the fork. The electronics in the unit sense this change and produce an output which can be used for indication or control. This type of switch is suitable for many situations requiring level detection, including pump control, high or low-level alarms, and detection of an interface between two different materials. Typical industrial uses include pharmaceuticals, food and beverage, mining/metals, water and wastewater treatment, chemical processing, and refining. A remote amplifier option is available. The probe can be separated from the amplifier by up to 500 m. A high temperature extension allows the unit to handle process temperatures up to 150°C. Heavy-duty construction ensures years of trouble-free operation. There are a number of Smart communications options, including GosHawk, DeviceNet, Modbus, HART, and Profibus DP. There is also a remote GSM connection option. Any authorized user with a standard modem and GosHawk software can dial in, and then calibrate, test or check on the performance of the unit from anywhere in the world. • Operating Voltage - 7 - 30Vdc (residual ripple no greater than 100mV), 80 - 260Vac 50/60Hz • Stability - 0.01% of reading / °C • Operating Temperature - -40°C (-40°F) to 80°C (176°F)
