KELLER Pressure Japan List of Products and Services

The diameter of the data logger DCX-16 is just 16 mm, allowing it to be installed in tight spaces. With a long-lasting battery, it can continuously measure pressure (water level) and temperature for an extended period (up to 4 years with a measurement frequency of once per hour). The logger can be configured using the included dedicated software for measurement intervals, incident management, delayed measurement start, and more. The recorded data can be displayed in graphs or charts, corrected using atmospheric pressure values, converted to filling levels or other units, and exported.

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.

The DCX-22 ECO data logger is a low-cost model of the high-precision DCX-22 data logger. With a 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 (for measurement intervals, incident management, delayed measurement start, etc.), and the recorded data can be displayed in graphs or charts, corrected using barometric values, or exported by converting to fill levels or other units.

The data logger DCX-22 AA measures water level (pressure) by correcting atmospheric pressure changes through the placement of two absolute pressure sensors divided between the measurement unit and the communication unit. Unlike gauge pressure systems, it does not require an open atmospheric tube, making it resistant to humidity and suitable for immersion. With a long-lasting battery, it can continuously measure water level (pressure) and temperature over an extended period (up to 10 years at a measurement frequency of once per hour). The logger allows for setting measurement intervals, incident management, delayed measurement start, and more using the included dedicated software, and the recorded data can be displayed in graphs or charts, corrected using atmospheric pressure values, and exported by converting to filling levels or other units. 【Features】 〇 φ22mm water depth and temperature data logger 〇 Durable SUS316L housing 〇 Configuration, data reading, and visualization possible on PC using dedicated software

The data logger DCX-25PVDF is specially designed for measurements in highly corrosive liquids such as brackish water and sewage. The housing is made of PVDF (polyvinylidene fluoride), and the pressure sensor material can be selected from Hastelloy C-276 or titanium 6AL-4V. With a 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 logger can be configured using the included dedicated software for measurement intervals, incident management, delayed measurement start, and the recorded data can be displayed in graphs or charts, corrected using atmospheric pressure values, and exported by converting to fill levels or other units.

The data logger DCX-38 is a water level meter for low water level measurements. It can detect water levels with an overall accuracy of just 1 mm (measurement range of 0.5 m water column, compensation temperature range of 10 to 40°C). With a 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 logger can be configured using the included dedicated software for measurement intervals, incident management, delayed measurement start, and more. The recorded data can be displayed in graphs or charts, corrected using barometric values, and exported converted to fill levels or other units. Silica gel prevents moisture intrusion into the sensor.

The data logger DCX-22-CTD measures not only water level but also water temperature and conductivity. With a long-lasting battery, it can continue to record measurement results for an extended period (up to 10 years with a measurement frequency of once per hour). By selecting the optional PT1000 temperature sensor, it achieves a temperature accuracy of ±0.1°C. Conductivity can be measured within the selected range (0.2/2/20/200 mS/cm) with an accuracy of ±2.5%. The logger can be configured using the included dedicated software for measurement intervals, incident management, delayed measurement start, etc., and the recorded data can be displayed in graphs or charts, corrected using atmospheric pressure values, or exported by converting to fill levels or other units. 〇 DCX-22 CTD: Absolute pressure type without a bench tube 〇 DCX-22 (SG/VG) CTD: VG is a general design using gauge pressure sensors (SG is shielded gauge pressure)

The data logger DCX-22AA-CTD measures not only water level but also conductivity in addition to water level. By separating two waterproof absolute pressure sensors into the measurement unit and the communication unit, it corrects for changes in atmospheric pressure and outputs the water level (pressure). Unlike gauge pressure systems, it does not require an open atmospheric tube, making it resistant to humidity and allowing for immersion. With a long-lasting battery, it can continue to record measurements over an extended period (up to 10 years with a measurement frequency of once per hour). The logger can set measurement intervals, incident management, and delayed measurement start using the included dedicated software, and the recorded data can be displayed in graphs or charts, corrected using atmospheric pressure values, or exported by converting to fill levels or other units.
