Air Flow Sensors
Air flow sensors provide instantaneous flow information for the compressed air supply of your applications. Sensors may have integrated displays, or remote units with separate ouput monitors. Displays may be mult-line and multi-color, offering more information with better visibility. Digital and analog outputs characterize operational conditions in useful ways. Features include multiple flow ranges, enclosure ratings up to IP65, and IO-Link capability.
Air Management System
The Air Management System automatically regulates and isolates the compressed air provided to a machine to improve efficiencies during periods of inactivity. The unit generates pressure, flow, and temperature data to characterize normal operating conditions and identify trends to both compare with similar machines and enable preventative action to maintain optimal system performance. The unit does not require reprogramming of the user's PLC to operate, making integration both simple and cost effective. The high-resolution data is accessed by the PLC via fieldbus and SCADA packages via OPC UA. Using OPC UA and wireless systems, the Air Management System can be added without connector to the PLC or changes to PLC programming.
Liquid Flow Sensors & Switches
Liquid flow devices include instantaneous flow sensors and mechanical flow switches giving an ouput signal at a set point. Sensors within the collection are optimized for a variety of conditions, including compatibility with water, coolant, or chemicals; detection method; space constraints; and manifold configuration. Outputs range from simple ON/OFF confirmation signals, mA or V analog, or digital IO-Link. Review the categories to select a product best suited for your application.
Auto Switches
SMC offers a variety of auto switches for actuators and air grippers. Reed and solid state switches are available in a general purpose type or with 2-color indication, which allows the optimum operating position to be determined by the color of the light. Solid state switches are also available in 2-color indication with diagnostic output, water resistant 2-color indication, built-in OFF-delay timer (200 ms), magnetic field resistant, heat resistant and wide range detection configurations. Various lead wire lengths are available.
Electronic Regulators
Electro pneumatic air regulators control air/vacuum pressure steplessly in proportion to an electric signal. They are light weight in design with a bright and easy to read LED display. The monitor output is available either as analog output or switch output.
Water Flow Control
FC3W is a flow controller for water between 0-50°C. A motor driven adjustable flow valve works together with feedback from a Karman vortex flow sensor to establish a flow rate corresponding to an analog input signal. When a single water supply source is divided into multiple lines, the flow rate between lines can be inconsistent. FC3W controllers can adjust flow on each line to a constant rate. Power, control, and error status LEDs confirm operation. The device is also grease free and IP65 rated. Please be aware that FC3W does not include a flow shutoff feature. Pair the controller with a VXZ 2-port solenoid valve to stop flow for any reason. Meets CE, UKCA and RoHS certifications.
Air Flow Controllers
Air flow controllers combine a valve with a flow sensor for confirmation. Control electronics receive an input signal that corresponds to a target flow rate. Air flow is measured, then the valve is opened or closed until the value matches the target rate. Several methods can be used to actuate the valve, depending on the product’s design requirements. Devices in this category may include an integrated or remote display, IO-Link protocol, M12 or D-sub connector, switch output and a range of flow rates. Applications include semiconductor manufacturing, welding, fabrication, painting, or food packaging.
Temperature & Humidity Sensors
The PSH Condensation Checker monitors temperature and moisture in a compressed air or non-corrosive gas supply line. The sensor identifies whether damaging condensation is a risk to the connected equipment. The detected results are displayed as percent relative humidity and temperature values. Both values can be displayed simultaneously if desired. The sensor can also respond to the detected values with display color changes and digital switch, outputs, signaling whether the values are within or outside the setpoint ranges. Values can be read and settings changed directly at the sensor, or remotely through analog voltage or IO-Link. The enclosure is IP65 rated and meets CE and RoHS standards.
