Strong in durability and wear resistance, ideal for sewage pump stations and manhole pumps!

The 26KyX series water level gauge is a submersible water level gauge specially developed for sewage and wastewater applications. It features a diaphragm made of Kynar with PTFE properties, providing resistance to viscous media along with excellent hardness and abrasion resistance. The 26KyX water level gauge can be easily installed in harsh environments without the need for expensive protective cages that take up space. Measurement results can be obtained via an RS485 interface, as well as through analog signal output via a built-in D/A converter, allowing for scaling settings (modification of the water level range). A version with a built-in lightning protection device is also available (optional). 【Features】 - Anti-fouling diaphragm design - Body material made of SUS316L - RS485 serial communication - Accurate correction technology

• Pressure

Low-cost immersion type water level gauge with a diameter of 21mm.

The 26Y series water level gauge is low-cost yet offers high accuracy and excellent long-term stability. It is available in absolute pressure or gauge pressure types (using an open atmospheric pipe). The startup time is quick at just 5ms, making it ideal for data logger applications. With the built-in lightning protection option, it can be used in various harsh environments such as rivers, wells, and boreholes. It features excellent temperature characteristics due to digital correction of output errors caused by temperature changes.

• Other measurement, recording and measuring instruments

High-precision automatic water level data collector, 100% waterproof type.

The DCX-22 data logger achieves higher accuracy than other narrow-diameter loggers. With its long-lasting battery, it can continuously measure water level (pressure) and temperature over an extended period (up to 10 years with a measurement frequency of once per hour). The data logger can be configured using the included software (measurement intervals, incident management, delayed measurement start, etc.), and the recorded data can be displayed in graphs or charts, corrected using atmospheric pressure values, and exported converted to fill levels or other units.

• Pressure

Small pressure sensor with welded structure covering from 0 to 10 kPa up to 0 to 100 MPa!

The welded structure small pressure sensor 23SY/25Y is designed to meet the advanced and diverse requirements of industrial applications, including pressure range, pressure connection, output signal, and electrical connection (25Y features a flush diaphragm structure). The modular concept allows for high flexibility in specifications and enables quick response times. A temperature sensor is integrated into the circuit, correcting errors caused by temperature changes and contributing to improved overall accuracy. We can also offer intrinsically safe explosion-proof types 23SYEi and 25YEi. 【Features】 - Wide temperature compensation: ± 0.7 %FS @ -10 ~ 80℃ - Minimum pressure range starting from 10 kPa - Excellent long-term stability - Robust SUS housing - Option: Intrinsically safe explosion-proof type (23SY-Ei) 【Technology】 - Piezo-resistive pressure sensor - Welded structure without internal seals - Analog output: 4 ~ 20 mA, 0 ~ 5 V, 0 ~ 10 V, etc.

• Pressure

High-precision pressure sensor with RS485 digital output. Atmospheric pressure range (800 to 1200 hPa) is also available!

The pressure sensor 33X achieves an extremely high accuracy of 0.05% full scale (FS) in the temperature range of 10 to 40°C through a mathematical correction method. An additional option for high precision of 0.01% FS is also available. In addition to a digital RS485 interface, analog current or voltage outputs can be obtained. 【Features】 - Accuracy of ±0.05% FS in the temperature range of 10 to 40°C - Standard dual outputs of digital RS485 and analog output - Analog output can be range-adjusted via digital RS485 - Available in barometric range type (800–1200 hPa) and differential pressure range type (from 0–30 kPa to 0–3 MPa) - Temperature range of -20 to 125°C (optional -40°C also available) - Excellent long-term stability 【Technology】 - Piezo-resistive pressure sensor - Correction technology using a mathematical model to produce accurate pressure values

• Pressure

±0.05% accuracy / Digital pressure gauge with logging function, explosion-proof type available

The high-precision digital pressure gauge LEO Record can record pressure and temperature for extended periods thanks to its memory function. The data logger can be connected to a computer via an RS485 interface for reading the recorded data. The current pressure value can be displayed in multiple pressure units. It is powered by a 3.6V lithium battery. An intrinsically safe explosion-proof type is also available. 【Features】 - Can record pressure and temperature for long periods - High precision (±0.05%FS @ 20–25 °C) - Ultra-low power consumption, long battery life - Can display in various pressure units (bar, mbar, hPa, kPa, MPa, PSI, kg/cm2, cmH2O, mH2O, etc.) - Zero point calibration via button - Intrinsically safe explosion-proof type available

We would like to express our congratulations on the continued prosperity of your esteemed company. Our company will be exhibiting at the following trade show, where we will be showcasing a number of products, including our new product, the Packaging Container Air Leak Test (Pin Hole Inspection) Device | MSQ-2003 series. We sincerely apologize for the inconvenience during your busy schedule, but we would like to cordially invite you to attend this event. 【 Trade Show Name 】 【 Dates 】 【 Venue/Booth Number 】

We will showcase our new product "BLFF," a palletizing foam gripper that weighs only 1.9 kg and measures 350mm×250mm, ideal for bulk picking. We will also introduce various products that cater to different work applications, including durable suction cups and solutions for bag handling. Additionally, we are implementing energy-saving proposals by replacing ejectors to reduce compressed air consumption, which has become a challenge in many industries. If you have any issues with adhesion or transport, please feel free to consult with us at the venue. ■ Lightweight Foam Gripper for Collaborative Robots "CVGC Series" Despite weighing only 1.9 kg, this gripper has a theoretical lifting force of 100 kg, maximizing the payload capacity of collaborative robots. ■ Gripper for Films This gripper is designed to transport thin films gently, minimizing marks left on the surface. By utilizing 3D printing, we can accommodate highly flexible shape designs tailored to specific workpieces and applications. ■ Energy Saving Comparison Panel "Why does a single ejector consume less compressed air compared to a multi-stage ejector?" You can actually verify the differences in compressed air consumption through a comparative display using a flow meter and actual equipment.
