compactdigitalstainless steel

Range:1cm/s～150cm/s (water) Output signal: 1 relay/2-way PNP/2-way NPN (optional) Features • Optional power supply 24VDC or 220VAC • OLED LCD screen, switchable display between the progress bar and digital display • All stainless steel housing, IP67 protection • Temperature compensation • 2-way PNP : 2-way NPN i, 1 relay output are optional • No moving parts, maintenance-free • Switch output, control point setting continuously on panel • Compact size, support inverted display • Mounting joint can be equipped with different interfaces for a variety of pipe diameters requirement SPK81 flow switch is an intelligent thermal diffusion principle-based flow monitoring sensor. It adopts ARM processing core and combines with high quality sensors and dedicated circuit. With temperature-compensation and calibration, it can ensure measurement accuracy in the case ofwater temperature change. It is available for real-time monitoring of pipe water flow. It can be used for cooling or lubrication system flow monitoring to realize pre-warning and protection for critical equipment when there is flow fault. It uses fully enclosed design, stainless steel construction to adapt to a variety of application environment. It is with over-voltage, over-current and reverse polarity protection function. With self-luminous OLED screen, it allows switchable display between the progress bar and digital display numbers. SPK81 supports quick action point set, also it has display inversion function that enables installation in any direction, and no need for frequent adjustment and maintenance.
