1 INTRODUCTION
The SERIES 2000 and SERIES 2000-SAN are solid-state pressure- and level transmitters
based upon a bridge resistive silicon sensor, with a very high burst pressure. The sensor
element is mounted in a stainless steel foot. A very strong stainless steel "flush" diaphragm
protects the sensor from the process medium. Special oil fills the chamber surrounding the
sensor and transfers pressure from the flush mounted diaphragm to the sensor.
Pressure on the sensor element creates a very small deflection of the silicon substrate and
bridge network. The resulting strain in the silicon resistors causes a change in the bridge
resistance that is proportional to the pressure applied. The transmitter electronics detects this
change in bridge resistance and converts it into 4-20 mA. The amplifier system is based on a
single Integrated Circuit, which ensures a perfect linearity in the 4-20 mA output.
Together with the Klay flush diaphragm technology the long term stability is perfect.
The Series CER-2000 are "All Stainless" pressure transmitters based on a ceramic pressure
cell, with very high burst pressure. These transmitters do not have oil filling.
The Series 2000, 2000-SAN, CER 2000 and Hydrobar I are available as SIL2, proven in use
(Option G200).
1.1 DESCRIPTION SERIES 2000-SAN
The SERIES 2000-SAN are specially designed with a flush mounted diaphragm so they fully
meet the needs of the food, pharma and chemical industries.
The Series 2000-SAN is available as 3-A version (Sanitary Standard - Option G153) and
EHEDG (Sanitary standard –Option G150). Standard the wetted parts are made of SS 316,
other materials are available, like Hastelloy C. Various process connections can be delivered,
such as Tri-Clamp (1,5”, 2” and 3”), SMS (1,5” and 2”), dairy milk couplings (DN 25, 40 and 50),
flanges (DIN and ANSI) and sanitary weld-on nipples (ø 48, 62 and 85 mm.)
1.2 DESCRIPTION SERIES 2000
The SERIES 2000 are specially designed for the pulp- and paper or similar industries, where
clogging is a problem. The very compact construction of the SERIES 2000 permits flush
installation with the tank- or pipe wall. Standard the wetted parts are made of SS 316, a lot of
other materials are available.
All transmitters are fully temperature compensated, which means that various process
temperatures have nearly no effect on the accuracy of the output signal. When a failure occurs,
the transmitter is repairable. However, for optimum accuracy the transmitter has to be send
back to the factory.
1.3 DESCRIPTION PERAMIC "S" (SERIES CER-2000)
The Series CER-2000 are pressure transmitters based on a ceramic pressure cell, which can
be used for all gauge- and absolute pressure measurement on steam, liquids and gases.
These transmitters do not have oil filling.
1.4 DESCRIPTION (SERIES 2000-HYDROBAR)
The SERIES 2000-Hydrobar is a complete range of submersible level transmitter for top
mounting. The 2000-Hydrobar can be used in fluids like waste water, mud, pulp and chemicals.
As standard the cable material is polyethylene. The connections for the wetted parts from the
2000-Hydrobar to the cable are from Viton® FKM.
1.5 BAROMETRIC REFERENCE
The SERIES 2000-SAN is in basic a so-called "relative transmitter" which means that
barometric changes will not affect the zero (4 mA). The venting (4) is placed in the cover of the
housing and is the barometric reference to atmospheric. The venting must be kept clean.
