Description
Pressure Transmitter 33X – a pressure transmitter that has gained wide recognition and distribution due to its stability and highest accuracy of 0.01% FSO. Often, during production or testing, the customer must be confident that the products or services they provide meet the highest standards. Therefore, a high-precision pressure sensor must be chosen carefully.
This series of pressure transmitters was developed for industrial applications where special requirements for measurement accuracy and stability are demanded. Measurement ranges from 0.1 to 2000 bar, suitable for both liquids and gases.
These transmitters use KELLER Series 10 sensors, which have proven their reliability and superiority in millions of different applications worldwide. Each sensor undergoes calibration and testing across the entire range of measured pressures and operating temperatures.
The flat diaphragm of the 35X series sensor allows measurements in thick, viscous liquids, as a larger active surface is engaged. Additionally, the flat diaphragm can be easily cleaned if necessary. The 33X/35X series pressure transmitters guarantee that measurements throughout the entire process from start to finish will be made with maximum accuracy and quality. The special Keller CSS30 software allows displaying readings on your PC screen, as well as making necessary adjustments to the sensor settings, such as changing measurement units, zero adjustment, and recalibration of the entire sensor range.
The high-precision pressure sensor by default has a digital RS485 output but can also be equipped with a digital CANopen or an analog output of your choice: 4…20 mA / 0…10 V / 0…2.5 V / 0…5 V / 0.1…2.5 V. Through the digital output, in addition to the pressure signal, the temperature signal from the sensor can be read, which can be useful for static processes.

PR – is a relative pressure transmitter, zero reading at atmospheric pressure. It can be used for measuring both gauge pressure and vacuum pressure.
PAA – is an absolute pressure transmitter.
PA – is a gauge pressure transmitter (zero at 1 bar abs.). It is suitable for use where atmospheric pressure changes can be neglected (for ranges above 10 bar) or where a hermetic sensor is required.
