The Series 23SX is a high precision piezoresistive pressure transmitter designed to combine the impressive features of the 23SY and 33X series pressure transmitters. 23SX Pressure Transmitter features a fully welded design of the 23SX with the highly accurate and scalable digital compensated electronics of the Series 33X. Offering a total error band of ±0.25% over the full -10 to +80°C compensated temperature range with 4-20mA or 0-10V outputs with RS485 Communications available. All RS485 units are reprogrammable using the Control Center Series 30 software, which allows for setting the analogue outputs range and setting new zero and gain for the transmitters.
In the 23SX series high-precision pressure transmitters, temperature dependencies and non-linearity are precisely compensated for by means of a mathematical model in the microcontroller. In addition to the RS485 interface with Modbus RTU protocol, there is also the option of outputting the measurement results as a scalable analogue signal via the integrated D/A converter. The fully welded construction without internal seals is suitable for dynamic applications. Only stainless steel is in contact with the media.
