DIN-Panel-Mount Electrically Actuated Counters with Output Relay

For quick installation, this counter fits standard DIN panel cutouts. Wire it up to an electrical pulse-emitting switch, sensor, or encoder for use on machine tools, packaging machinery, or other equipment. An output relay sends a signal to another device when the counter reaches a set point. The signal can start/stop a process or trigger an alarm. A gasket provides protection from direct water sprays (meets IP65). UL Recognized Component, C-UL Recognized Component, and CE marked, this counter meets American, Canadian, and European safety standards.

Sanitary Rotary Motion Position-Measuring Transmitters
Also known as encoders, these sanitary transmitters convey motion to an electrical signal that conveys distance, direction, and speed. They’re often used in control systems to automate servomotors, robotics, and assembly machines in sanitary environments such as food and pharmaceutical plants. Made of corrosion-resistant stainless steel, they won’t rust from frequent washdowns with harsh cleaners. These transmitters are sealed and have a highly polished surface, leaving no room for bacteria to grow and making them easier to clean. They’re rated IP67 for protection from dust, high-pressure jets of water, and submersion in up to a meter of water for 30 minutes.
To achieve a 4X resolution increase, use these transmitters with a controller that has quadrature detection.
Transmitters with three mounting holes are designed to fit on a three-hole servomotor face.
Connect transmitters to counters and controllers with cables (sold separately).
Use a flexible shaft coupling to connect the transmitter shaft to a drive shaft.

Remote-Reading Multifunction Chemistry Meters
Take multiple water-chemistry and temperature measurements in hard-to-reach places from up to 3 feet away. Often used in tap water and wastewater, these meters work in both clean and dirty liquids. Automatic temperature compensation standardizes readings to 77° F to prevent inaccurate results in changing temperatures. The data hold function freezes the current reading on the display. For easy viewing, temperature and chemistry measurements appear on the same screen. These meters are IP57 rated, so they resist dust and withstand temporary submersion. They cannot be sold to Canada due to import regulations.
To maintain their accuracy, all have a calibration button and some also come with calibration solutions.
Conductivity, salinity, temperature, and total dissolved solids (TDS) meters take four measurements at once. Conductivity measures the concentration of salts, nutrients, chemicals, and other substances. Salinity measures the amount of dissolved salts. TDS determines the contaminant levels. The stainless steel sensor is durable and resists breaking.
Oxidation reduction potential (ORP), pH, and temperature meters take three measurements. ORP measures the amount of dissolved oxygen in liquids. It determines how efficiently a liquid breaks down contaminants.

Air Particle Counters

Check your indoor air quality (IAQ) by measuring the amount of particles present. These counters are often used to monitor dust levels in workshops, check for particles in classrooms, and measure filter efficiency in HVAC systems. The sensor probe detects and identifies particles of six different sizes, helping you confirm that your clean room complies with ISO Class requirements. First, use the zero count filter to establish a baseline before taking a sample. Then, either measure the amount of air particles detected within a set time range or the amount of air particles detected within a certain air volume. Counters store up to 10,000 readings in their internal memory, and you can transfer data to your computer via Ethernet or USB connection—no special software required. Compact, lightweight, and battery powered, these counters are portable and able to operate in tight spaces. They’re CE marked as compliant with European health, safety, and environmental standards.

Sanitary Conductivity Sensors




Often used to save rinse water in beverage and pharmaceutical lines, these sensors test the amount of chemicals, cleaners, and other substances in liquids by measuring how well the liquid conducts electricity. They’re 3-A and European Hygienic Engineering and Design Group (EHEDG) certified, thanks to their design that’s easy to keep clean. Highly polished, they limit where bacteria could grow. They also withstand washdowns with hot water, chemicals, and cleaners common to sanitary lines because of their PEEK probe, stainless steel body, and IP ratings. Their IP ratings also mean they’re dust tight and won’t fail if briefly under water. All are FDA compliant to safely touch food.
These sensors work with IO Link, Hart, and 4-20 mA analog output to connect to remote displays and programmable logic controllers (PLCs), making them good for hard-to-reach areas and frequent application changes. This also means they’ll set off alarms and trigger cycles to start and stop in automated systems. With the touchscreen, program each color of the display to alert you to errors, completed cycles, and other events. Both the head and the display rotate to view readings from the best angle.
Highly accurate, these sensors test almost any liquid. They also measure temperature—no need for a separate sensor. To compare readings as temperature changes, they automatically standardize readings at 77° F. All meet European safety standards, since they’re CE marked.
Use quick-clamp adapters to connect these sensors to quick-clamp sanitary tube fittings.
