Piezoresistive Pressure Tranitters Series 26 W

For Level- and High Precision Pressure Measurements

The Series 26 W tranitter utilises the Series 10 piezoresistive capsule, which is housed inside a submersible 316 L stainless steel body as standard.

For corrosive applications hastelloy diaphragms and other materials are available as options. Series 26 W vented gauge versions have cable with integral vent tube. These tranitters are fitted with durable PE cable.

Pressure Ranges

0,2...20 bar (relative)

Output

0...10 V
0...20 mA
4...20 mA

Linearity

t. 0,2 %FS

Stability, Range 500 mbar
Stability, Range > 1 bar

t. 1 mbar
t. 0,1 %FS

Intrinsically Safe Piezoresistive Pressure Tranitters
Series 23 (S)Y Ei / 25 Y Ei / 26 Y Ei

For gas and dust atmospheres

These piezoresistive pressure tranitters are approved for use in highly explosion risk areas of group II (gas and dust).

The Y-line tranitters have an extremely all 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. The TK zero and TK compensation values are calculated for each field and programmed into the additional circuit. During operation, these values are fed into the ogue signal path depending on the temperature. Each temperature is the „calibration temperature” for this tranitter. The accuracy thereof is mainly determined by linearity. 120 fields are available, representing a possible temperature range of 180 K. The wider the temperature range, the greater the amount of testing that is needed to minimise the inaccuracy of the mathematical model.

Pressure Ranges	0,2...1000 bar
Output	4...20 mA 0…5 V 0…10 V
Accuracy	&plun; 0,25 %FS
Storage Temperature	-40…100 °C

Note:
The Series 23 (S) Ei, Series 25 (S) Ei, 26 Ei have been replaced by this Series.

Capacitive Tranitters Series 46 X / 46 X Ei

For Water Level Measurements

The Series 46 X combines the ceramic measuring cell for low pressure ranges with the µP-electronics of the dial Series 30 pressure tranitters. The signal values of the pressure- and temperature sensors are determined by a polynomial compensation. The values can be shown and stored on a PC and can be reprogrammed. A reference tube integrated in the cable connects the referential chamber of the sensor with the ambient pressure.

This pressure tranitter is also available as intrinsically safe version (Series 46 X Ei). It is used in explosion exposed areas, where the categories 1 and 2 are required.
