Overview

SUCH digital pressure transmitter features a backlit LCD display and supports DC12V, 24V, and DC12-36V power supplies. It can output currents of 4-20mA, voltages of 0-5V/1-5V/0-10V, and RS485 signals. Compact and lightweight, it offers excellent vibration and shock resistance. The pressure sensor measurement range covers -0.1 to 100MPa (-1 to 1000bar/-14 to 14503psi), operating temperature ranges from -40°C to +60°C, frequency response from 5kHz to 650kHz, and IP65 protection, making it suitable for pressure measurement in a variety of working conditions, including hydraulic, oil, and pneumatic pressure.

Feature

Precise measurement: Built-in temperature compensation ensures stable and reliable operation in a variety of environments.
Rugged and durable: The integrated cast steel construction is vibration- and shock-resistant, making it suitable for harsh operating conditions.
High-grade protection: IP65 protection ensures effective dust and water resistance, extending its service life.
Integrated display: High-definition LCD screen provides intuitive readings, eliminating the need for an external display and facilitating on-site monitoring and operation.

Note: For the output signal RS485, it is only a 485 communication protocol, if you need the data to be received from the PC through the RS485 port, then the PC used should be a PC for industrial application, which can support 485 communication function (such as touch screen HMI upper computer, etc.), A USB to 485 communication interface is also needed to connect the sensor to the PC.

FAQ

Q1: What signal outputs does this pressure transmitter support? ❯

It supports current signals (4-20mA/0-20mA), voltage signals (0-5V/1-5V/0-10V), and RS485 digital signals, meeting the needs of various control systems.

Q2: Is a higher sensitivity for a pressure sensor always better? ❯

Not necessarily. Within the sensor's linear range, high sensitivity facilitates signal processing, but excessively high sensitivity can amplify external noise, affecting measurement accuracy. Therefore, a sensor with a high signal-to-noise ratio should be selected.

Q3: How should I choose a pressure sensor in a high-noise environment? ❯

We recommend choosing a digital pressure sensor with a high signal-to-noise ratio and strong anti-interference capabilities to prevent irrelevant external signals from influencing the measurement results.
