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.

LEO 1 -
KELLER AG für Druckmesstechnik
LEO 1 is a micro-processor controlled, accurate and versatile digital pressure measuring instrument with integrated fast peak-, max.- and min.-function.The instrument is used in two modes:
-
LEO Record (Ei) -
KELLER AG für Druckmesstechnik
LEO Record is an autonomous battery powered instrument with digital display designed to record pressure and temperature over long periods. Both the piezoresistive LEO Record as well as the capacitive LEO Record (ideal for low pressure ranges) offer the following advantages:
-
EV-120 -
KELLER AG für Druckmesstechnik
The EV-120 is a digital pressure indicator, designed for use in conjunction with a KELLER Series 30 transmitter. Together, these two instruments build a highly precise pressure measuring device. The EV-120 interrogates the Series 30 transmitter and updates the display two times every second. The display shows after turn-on the full-scale pressure range of the transmitter and then the actual pressure reading.
-
LEO 3 -
KELLER AG für Druckmesstechnik
LEO 3 is a micro-processor based transmitter with digital double-display for pressure (top display) and for the output signal (bottom display). The display is powered from the 4...20 mA current loop. Functions:
-
Series 2 Mi -
KELLER AG für Druckmesstechnik
Developed for measuring hydrodynamic and aerodynamic pressures. A silicone drum protects the measurement cell from the influence of vibrations and fast acceleration.
-
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.
-
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.
-
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.
-
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.
-
KELLER AG für Druckmesstechnik
Designed for measuring flow rate and ram pressure in pipework.The probe can be advanced a number of metres into tight canals thanks to dimensions ranging from ø 1,32 mm to ø 2,64 mm and a highly flexible cable.
-
DCX-38 VG -
KELLER AG für Druckmesstechnik
The DCX-38 VG is an autonomous instrument for recording water level with a high resolution and full scale ranges as low as 0,5 mWC / 50 mbar. It features a rugged, gold-plated ceramic diaphragm for outstanding long-term stability and stainless steel housing with user serviceable battery for long service life.
-
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.
-
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.
-
LEX 1 -
KELLER AG für Druckmesstechnik
LEX 1 is a micro-processor controlled, accurate and versatile digital pressure measuring instrument with integrated Max.-/Min.-function for calibration and testing purposes.
