Autonomous Data Collector
DCX-25 PVDF
KELLER AG für Druckmesstechnik
The DCX-25 PVDF is an autonomous, battery powered instrument designed to record water depth (pressure) and temperature over long periods. The housing is made of polyvinylidene fluoride and the sensing diaphragm is available in either Hastelloy C-276 or titanium 6AL-4V. This combination of wetted materials ensures compatibility with even the most aggressive media.

Piezoresistive Transmitters For Automotive- and Industrial Applications
Series 22 DT
KELLER AG für Druckmesstechnik
Series 22 DT was developed and homologated specially for use in so-called "bivalent" vehicles fitted with engines for combined natural gas/gasoline operation. The unconventional design with a small mass swept by the flow results in a fast response with temperature changes, the temperature being measured by an NTC or PT sensor located directly behind the stainless steel separating diaphragm.

Piezoresistive Miniature Pressure Transmitters
Series 21 PY "Pisello"
KELLER AG für Druckmesstechnik
Ultramodern welding techniques and advances in the miniaturization of electronic circuits now make it possible to manufacture a pre-insulated, piezoresistive micro-transmitter with properties that were no more than a dream 10 years ago.

Autonomous Data Collector
DCX-16 (VG, SG)
KELLER AG für Druckmesstechnik
The DCX-16 is an autonomous, battery-powered data collector in a stainless steel housing with a very small diameter of only 16 mm. In applications where a small probe diameter is an advantage, the logger can record the water level (pressure) and the temperature over long periods.

Pressure Transmitters For Industrial Applications
Series 21 Y
KELLER AG für Druckmesstechnik
The Y-line transmitters have an extremely small temperature error. This is achieved using an additional circuit containing a temperature sensor that subdivides the temperature range into fields that are 1,5 Kelvin (K) wide.

Data Collector for Water Levels
DCX-22 AA
KELLER AG für Druckmesstechnik
The data collector DCX-22 AA measures and records ground water levels using KELLER's two sensor AA-technology (absolute-absolute). The submersible depth sensor measures the water level. Barometric pressure variations are measured and compensated with the built-in waterproof air pressure sensor which is mounted in the electronics housing at the top of the borehole.

Autonomous Capacitive Data Collector
DCX-38
KELLER AG für Druckmesstechnik
The DCX-38 data loggers are designed for water level measurements with a high resolution in the mbar range. They can detect water levels with a total error band of just 1 mm (measuring range 0,5 m water column, compensated temperature range -10...40 °C). Thanks to their long-life battery, they can keep measuring the water level, water pressure and temperature for years (up to 10 years at a rate of one measurement per hour). The logger can be configured using the supplied software (measurement interval, incident management, delayed measurement start etc.) and data that has been read can be displayed in a graph or chart, converted into fill levels or other units, and exported.

Pressure Transmitter For Industrial Applications, Ratiometric Output
Series 21 C
KELLER AG für Druckmesstechnik
The C-series transmitters are noted for their ability to deliver high accuracy over a wide temperature range. This is achieved by means of mathematical modelling of the sensor characteristics and digital compensation. In order to do this, each transmitter is gauged over pressure and temperature, programmed and checked after calibration in the same test set-up.
