Hawk FF Level Series – AS2-XXXX

Admittance Level Series Principle of Operation The probe of the Admittance Switch forms one plate of a capacitance circuit, with the vessel wall making the second plate. The dielectric constant of the product between the probe and the vessel wall will cause a change of capacitance as the level approaches the probe. The change is detected, amplified and used to switch a relay for indication or control purposes. A special circuit is used to ignore product build-up between the sensing probe (active element) and guard, and also between the guard and vessel wall.   Primary Areas of Application * Asphalt * Brewing * Cement * Chemical * Dairy * Edible oil * Fertilizer * Food & Beverage * Glass * Mining & Metals * Oil & Gas * Packaging * Paint * Paper * Pharmaceutical * Plastics * Power Generation * Refining * Semiconductor * Sugar * Textile * Water & Wastewater Features: * Excellent immunity to product build-up * Excellent temperature stability - no false trips * Non contact switching possible with many products * Simple ‘1-minute' setup * Remote sensor or Smart ‘all in one' types * Relay outputs: Smart probe (1) Remote (2) * Remote test function * Adjustable ON and OFF delays (0-20 sec) * Smart communication options: GosHawk, Modbus, HART, Profibus DP, DeviceNet, Foundation Fieldbus and Profibus PA * Remote GSM Connection option * Remote amplifier to probe separation up to 500 m (1640 ft) * Bright visual status indication on Probe * Independent housing alignment after mounting thread locked
