Overview

The pressure transmitter utilizes a high-performance silicon piezoresistive core and offers selectable output signals: 4-20mA, 0-5V, 1-5V, 0-10V, and RS485. The sensor's measurement range covers -0.1~100MPa (-1~1000bar/-14~14503psi). Its media temperature range is -40 to +60°C (-40 to +140°F), making it suitable for a wide range of pressure measurement applications, including air, water, and oil. SUCH sensor achieves IP65 protection and offers flexible electrical connection options, including DIN connectors, direct cable, or M12 circular connectors, to meet diverse operating requirements.

Feature

Strong Anti-Interference Performance: The digital circuit board design offers excellent resistance to electromagnetic interference. The damping design resists transient shocks and effectively prevents overload damage.
Gas-Guided Design: The gas-guiding structure ensures a more stable zero point, ensuring more accurate and reliable measurement results.
High Precision and Long Life: The sensor has high precision, stable performance in long-term use, and longer service life.

FAQ

Q1: What is the stability of a pressure sensor? ❯

The ability of a pressure sensor to maintain consistent performance over a period of use is called stability.

Q2: What factors affect the long-term stability of a pressure sensor? ❯

In addition to the sensor's structural design, this primarily depends on the operating environment, such as temperature, humidity, electromagnetic interference, vibration, and media characteristics.

Q3: Why should the operating environment be considered when selecting a pressure sensor? ❯

Different environments have different effects on sensors. It is important to select the appropriate model based on the actual operating conditions or implement protective measures to minimize environmental impacts to ensure long-term stability.

RS485 communication settings

Hi, I’m looking at the SUCH-PRES-P300 for a hydraulic pressure monitoring system and had a few questions about the RS485 communication. Does it use Modbus RTU? Also, what are the default baud rate, parity, and stop bit settings? Is the slave address fixed, or can it be changed? I’d also like to get the Modbus register map for the pressure reading if available.

A manager responded to this review

Hi, yes, the RS485 interface uses Modbus RTU. The default settings are 9600 baud, no parity, and 1 stop bit, with slave address 1. The address can be changed. Please refer to the communication protocol document for the Modbus register map.
