Flow switch for oil-based media flow-captor 4321.1x/xx The flow-captor type 4321.1x/xx is a flow monitor which is used in automation processes and other industrial applications where liquid media need to be monitored. The 432x-series offers “inline-models” that have been specially designed for installation in smaller pipe diameters. The sensor works according to the calorimetric measuring principle. The detection takes place inside the inline tube, whereby the sensor measures the flow velocity of the medium and converts it into an electrical signal. • for small pipe sizes from OD6 up to OD28 precise switching flow monitor with high accuracy even with very slow flows fully electronic analogue display of the flow condition and adjusted switch-point via LED chain separate adjustment of flow range and switching point no mechanically moved parts Control and display panel LED chain for display of flow speed Flashing LED for display of adjusted set-point Potentiometer for set-point adjustment Potentiometer for range adjustment from .3 to 3 m/s. LED to indicate the switching status Measuring range adjusted to 3 m/s = 100 % (9. LED) Set-point adjusted to 50 % of end value (5. LED) Flow speed equates 75 % (7. LED) Green LED is ON: Flow rate is above the adjusted set-point Free flow The sensor tube (length 200 mm) is made of stainless steel 316 and is an integral part of the inline flow-captor. The sensor element of the inline flow-captor is fitted to the out-side of the sensor tube. Since there is no element inside the tube, the sensor is non-intrusive to the flow. The robust housing is constructed of glass fibre reinforced PBTP (Ultradur ®). The electronics housing includes a full resin encapsulation. This series is available with sensor tubes in different sizes as 6 x 1, 8 x 1, 12 x 1, 18 x 1.5, 22 x 1.5 as well as 28 x 1.5 mm. For aggressive media other material can be offered on request. Mechanical connection Cutting ring couplings, to be ordered separately, have proven their value when mounting the sensor into pipe systems. By slightly tightening the swivel nut the v-shaped ring inside of the coupling cuts into the sensor tube wall and thus ensures a dense and reliable form closure. www.captor.de [email protected] DE-25377 Kollmar, Germany Tel.: +49 (0)4128 - 591· Fax: - 593 Sensors GmbH Strohdeich 32 [email protected] Tel.: +44 (1704) - 551684 · Fax: - 551297 Merseyside PR8 4DU, UK 66 Eastbourne Road, Southport Sensors Ltd.
