Product Details

I. Product Overview

The SIKA VHS02M0SKOTS07 is a VHS series paddle flow switch manufactured by German SIKA (Dr. Siebert & Kühn GmbH & Co. KG), featuring a metal version design with pipe section and equipped with a plug connector. This flow switch is based on the well-established mechanical paddle operating principle, used for monitoring the volumetric flow of low-viscosity media (such as water, oil, etc.) in pipes, protecting high-quality systems and installations from damage by ensuring minimum flow rate.

The SIKA VHS series flow switches feature a modular design, configurable for different nominal diameters and setpoint ranges. The wide temperature and pressure ranges, material selection and connection options ensure a high level of versatility. The flowing medium hits the plate secured to the end of a paddle, and the resulting dynamic pressure deflects the plate, triggering a microswitch through a mechanical transmission mechanism to output a switching signal. Thanks to different paddle lengths, the switch points can be configured for a wide switching range.

The VHS02M0SKOTS07 features a metal housing design (brass or stainless steel material), equipped with pipe section and plug connector, with a robust structure suitable for high maximum flow conditions. The product has protection class IP65, max. working pressure 25bar, medium temperature range -25~110°C, ambient temperature -25~80°C, switching capacity max. 1A/230VAC/26VA, setpoint tolerance ±15%, setpoint hysteresis 10~30%. This flow switch is widely used in heating equipment, industrial cooling circuits, water treatment, drinking water applications, lubricating oil systems, hydraulic systems, etc., serving as a reliable solution for ensuring system flow safety and equipment protection.

VII. FAQ

Q1: What is the operating principle of the VHS series flow switch?

A: The VHS series adopts a mechanical paddle (plate) operating principle. The flowing medium hits the plate secured to the end of a paddle, and the resulting dynamic pressure deflects the plate, triggering an internal microswitch through a mechanical transmission mechanism to output a switching signal. When the flow drops below the setpoint, the plate resets under spring force, and the switch contact returns to its original state. By replacing paddles of different lengths, the switch setpoint can be adjusted over a wide range.

Q2: Can this flow switch be used for oil media?

A: Yes. The VHS series flow switches are suitable for low-viscosity liquid media, including water, oil, etc. In oil applications such as lubricating oil systems and hydraulic systems, flow switches are commonly used to monitor oil flow, ensuring equipment is adequately lubricated and cooled, preventing equipment damage caused by low flow. For the specific applicable medium viscosity range and compatibility, please refer to the SIKA official technical documentation or contact via email for confirmation.

Q3: Can the setpoint be adjusted in the field?

A: The setpoint of the VHS series flow switch is mainly configured by selecting paddles of different lengths, and is set at the factory according to the selection. Some models may support field fine-tuning, but it is recommended to determine the setpoint range during selection and have it adjusted by professional personnel. The setpoint tolerance is ±15% and the hysteresis is 10~30%. For field adjustment, please refer to the product installation manual and operate by professional personnel.

Q4: Can you provide detailed configuration and selection support for this model?

A: Yes. Please contact via email with your application conditions, including measuring medium, medium temperature, working pressure, pipe diameter, flow range, required setpoint, process connection method, electrical requirements, explosion-proof requirements, etc. We will provide corresponding detailed configuration analysis, selection recommendations, installation guides and technical support.
