Advantages of Ziasiot pressure temperature indicator and controller
Melt pressure indicator and controller uses single-chip microcomputer as the control core, adopts SMT patch technology,switching power supply, control parameter self-tuning algorithm, sensor nonlinear high-precision change, electromagnetic compatibility design, high measurement and control accuracy, and strong anti-interference. pressure single display, temperature and pressure dual display are optional, multiple input signals, output signals, multiple appearance structures, small size, light weight. low power consumption etc. It is widely used in pressure and temperature display and automatic control in hydraulic, petroleum, plastic, rubber, printing and dyeing, textile and other industries.
These instruments are compatible with melt pressure transducers and transmitters with standard current/voltage outputs. Our transducer controllers offer zero and 80% span calibration capabilities to maintain accuracy over the life of the pressure sensor.
Types of pressure temperature indicator and controller
1. Pressure Indicator
Measures and displays the pressure of a system.
Applications: Hydraulic systems, pneumatic systems, and industrial machinery.
Example: A melt pressure indicator used in plastic extrusion to monitor molten plastic pressure.
2. Pressure Controller
Measures pressure and automatically adjusts it to maintain a setpoint.
Applications: Process control in oil and gas, water treatment, and manufacturing.
Example: A melt pressure controller in an extruder to regulate molten plastic pressure.
3. Temperature Indicator
Measures and displays the temperature of a system.
Applications: HVAC systems, food processing, and chemical reactors.
Example: A temperature indicator in a boiler to monitor steam temperature.
4. Pressure Temperature Indicator
Combines the functions of measuring and displaying both pressure and temperature.
Applications: Industrial processes where both parameters are critical, such as plastic molding and chemical processing.
Example: A pressure temperature indicator in a hydraulic system to monitor fluid pressure and temperature.
5. Melt Pressure Indicator
Specifically designed to measure the pressure of molten materials, such as plastic or rubber.
Applications: Extrusion, injection molding, and blow molding.
Example: A melt pressure indicator in a plastic extruder to ensure consistent product quality.
6. Melt Pressure Controller
Measures and controls the pressure of molten materials in real-time.
Applications: High-temperature processes like plastic and rubber manufacturing.
Example: A melt pressure controller in an injection molding machine to maintain precise pressure levels.
How Does a Pressure Temperature Indicator and Controller Work?
A pressure temperature indicator and controller operates through the following steps:
Measurement: Sensors measure the pressure and temperature of the system.
Pressure is measured using a diaphragm, strain gauge, or piezoelectric sensor.
Temperature is measured using thermocouples, RTDs, or thermistors.
Signal Conversion: The measured values are converted into electrical signals.
Analog signals (e.g., 4-20 mA or 0-10 V) or digital signals are transmitted to the controller.
Display: The pressure and temperature values are displayed on the indicator.
Users can monitor real-time data and make adjustments if necessary.
Control: The controller compares the measured values with the setpoints and adjusts the system accordingly.
For example, a pressure controller may open or close a valve to maintain the desired pressure.
A temperature controller may activate a heating or cooling system to regulate temperature.
