OEM Pressure Transducer Series 3 L to 10 L
Laser Welded Media Isolation Diaphragm
Series 3L...10L, a new range of transducers that benefit from smaller capsule dimensions and crevice free diaphragms. Keller has developed a new technique for laser welding very thin stainless steel media isolation diaphragms. The smaller crevice free transducers still retain all the traditional performance, stability, and quality, for which Keller is renowned.
Each transducer is supplied with a calibration sheet indicating sensitivity, linearity, zero offset, temperature errors and the compensation resistors to substantially reduce zero offset and zero temperature errors.
With the laser welded technology, transducers having diameters as low as 9,5 mm can be realised. Diameter is to some extent dependent upon the pressure range measured, low pressures require larger diameters, higher pressures can be achieved with smaller diameters. This is due to the expansion of the oil under temperature that creates an internal pressure due to the resistance of the diaphragm. The smaller the diameter, the higher the internal pressure and the more difficult is the zero compensation.

Digital Manometer dV-2 PS with Switch Outputs
User selected switching points and functions
The dV-2 PS is a sophisticated digital pressure gauge with two independent pressure switch outputs. The gauge employs KELLER’s proven microprocessor technology which produces highly accurate results. All readings are linearised and temperature corrected, to give an accuracy of 0,2 %FS.
There are two independent switches for High and Low control functions. These are solid state and therefore not subject to wear. The switch points are programmed directly from the two front panel buttons and a menu system. Alternatively, the dV-2 PS can be connected via the RS485 link to a laptop/PC, and configured using KELLER’s “Pressure Switch Console” software. User defined configurations can be stored on the computer for future reference. Pressure sequences can also be monitored and recorded on the PC for application diagnostic purposes using KELLER’s Read30 software.

Pressure Switch PA-22 PS
User selected switching points and functions
The PA-22 PS is a compact programmable pressure switch; it also has an analog transmitter output signal (0,5…4,5 V). It will continuously monitor a process via the analog signal. The switch functions can be used to activate alarms or control relays at predetermined pressure levels.
There are two independent switches for Hi/Lo control functions. These are solid state and therefore not subject to wear. Outputs are selectable PNP or NPN (factory set; to be specified upon order).
The optional dV-22 PP programmer (external supply) allows the user to change settings via two buttons and menu system. Alternatively, the programming unit is linked to a laptop/PC and can be used with KELLER’s “Pressure Switch Console” software.
