|
Relative Humidity |
0% to 95% RH |
|
Overpressure Limit |
2 to 10 times full scale without damage |
|
Volume Change |
Less than 0.16 cm³ |
|
Damping Time |
Time constant adjustable between 0.2 s and 32.0 s |
|

Advantages of Process Transmitter
Improved accuracy and stability:
Process transmitterrs use digital technology and microprocessors, resulting in higher accuracy and long-term stability.
Enhanced data communication:
Digital communication allows transmission of more information (status, diagnostics, history) than a simple 4-20 ma signal. Supports integration with distributed control systems and asset management software.
Greater flexibility and functionality:
Multiple output options (analog, digital) and ranges. Ability to perform complex functions, such as linearization, filtering, and signal processing.
Reduced maintenance costs:
Predictive diagnostics minimize unnecessary maintenance. Less frequent calibration and troubleshooting required.
Improved safety and reliability:
Accurate monitoring and diagnostics enhance plant safety by allowing prompt corrective actions. Fault detection reduces likelihood of unsafe process conditions.
The absolute and gauge pressure transmitter features stainless steel wetted parts, ensuring compatibility with a wide range of gases and liquids. Its robust construction enables reliable performance in harsh environments and demanding media conditions. With a compact housing diameter of just 19mm, the transmitter simplifies installation and saves space, making it ideal for industrial automation, process control, energy management, and environmental monitoring.
Full temperature and pressure compensation allows the absolute and gauge pressure transmitter maintains exceptional accuracy and stability across a broad temperature range of -40°C to 125°C.
Application of Process Transmitter
Industrial process & control: This absolute and gauge pressure transmitter is widely used in the chemical, pharmaceutical, and food processing industries for precise pressure monitoring and control in pipelines, reactors, and vessels. It supports both absolute and gauge pressure measurement to meet a variety of process requirements.
Energy management: The sensor ideal for natural gas pressure monitoring, compressor control, and hvac systems, ensuring efficient and safe operation while optimizing energy consumption.
Environmental monitoring & meteorological equipment: Integrated into weather stations, barometric pressure sensors, and altimeters to provide accurate atmospheric pressure data for environmental research and forecasting.
Automotive & test measurement: Applied in engine testing, brake systems, and fuel pressure detection to enhance vehicle performance, safety, and compliance with industry standards.
Medical & laboratory equipment: Used in ventilators, sterilizers, and laboratory pressure instruments to deliver reliable and precise pressure control for critical healthcare and research applications.
Process control instruments consist of three primary hardware components: the measurement and transmission unit, the actuator, and the controller. The measurement and transmission unit, commonly known as the transmitter, serves as the link between the sensor and the control system. In some cases, the transmitter and the sensor are integrated into a single device. Actuators, such as valves, execute control commands, while the controller (e.g., a PID controller) acts as the brain of the entire control system.
