Series 23SY

Product catalog summary

Overview: The Series 23SY is a piezoresistive pressure transmitter designed for high-demand applications. It features a robust stainless steel housing, excellent long-term stability, and compensation over the entire temperature range. Optional versions include intrinsically safe (23SY-Ei) and increased safety (23SY-En) models.

Specifications:

Pressure Ranges: 0…0.1 to 0…1000 bar, with both relative and absolute pressure options.
Accuracy: ±0.25% FS for pressures >0.3 bar, with a total error band of ±0.7% FS from -10 to 80°C.
Temperature Range: Compensated from -10 to 80°C, with optional extension to -40 to 125°C.
Materials: Stainless steel AISI 316L for pressure connections and diaphragms, with silicone oil filling.

Performance: The transmitter maintains a total error band of ±0.5% FS at 0 to 50°C and ±0.7% FS at -10 to 80°C for pressure ranges ≥2 bar. For smaller ranges (0.1 to 0.3 bar), the error band is ±3 mbar at 0 to 50°C and ±4.5 mbar at -10 to 80°C.

Electrical Data:

Connectivity: Available in 2-wire and 3-wire configurations with various analog interfaces (4…20 mA, 0…10 V, etc.).
Voltage Supply: Ranges from 8 to 32 VDC depending on the model.
Protection: Overvoltage and reverse polarity protection up to ±32 VDC.

Mechanical Data:

Pressure Connections: Options include G1/4 male, G1/4 female, 1/4-18NPT male, and G1/2 male.
Environmental Conditions: Medium temperature range from -20 to 125°C, with ambient temperature limits depending on the model.
Protection Ratings: IP67 for round plug connections, with other options available.

Conformity: The Series 23SY complies with CE, RoHS, ATEX, and IECEx standards, ensuring safety and reliability in various hazardous environments.

Accessories: Includes calibration certificates with 5 or 11 measuring points, and various mating plugs for different protection demands.
