Product Description

Product Description

Wiika Pgs21 

The Wiika Pgs21 is a state - of - the - art device that serves as a crucial link in industrial measurement and control systems. It is primarily designed for use in hazardous areas, where the risk of explosion due to the presence of flammable gases, vapors, or dust is a concern. The Pgs21 acts as an interface between the field sensors and the control system, ensuring that the signals transmitted from the sensors in the hazardous area are safely and accurately relayed to the control room.
This device is a type of isolated barrier, which means it provides electrical isolation between the hazardous area and the non - hazardous area. This isolation is crucial for preventing the transfer of electrical energy from the non - hazardous area to the hazardous area, where it could potentially ignite explosive atmospheres. The Pgs21 is also equipped with advanced signal conditioning and processing capabilities, allowing it to handle a variety of input signals from different types of sensors and convert them into standardized output signals that can be easily understood by the control system.

1. Functionality
1.1 Intrinsic Safety Function
One of the primary functions of the Wiika Pgs21 is to provide intrinsic safety. Intrinsic safety is a protection technique that ensures that any electrical or electronic equipment used in a hazardous area cannot release sufficient electrical or thermal energy to cause an explosion. The Pgs21 achieves this by limiting the electrical power and energy available to the field devices in the hazardous area.
It acts as a barrier, isolating the higher - energy control circuits from the potentially explosive field environment. The Pgs21 is designed to comply with international standards for intrinsic safety, such as IEC 60079 - 11. This means that it has been rigorously tested and certified to ensure that it meets the strict safety requirements for use in hazardous areas. By using the Pgs21, industrial facilities can significantly reduce the risk of explosions and ensure the safety of their personnel and equipment.
1.2 Signal Repetition and Transmission
Input Signal: The Pgs21 can receive a wide range of input signals from field sensors. Common input signals include 4 - 20 mA current signals, which are widely used in industrial instrumentation. It can also handle voltage signals within a specified range. The input impedance of the Pgs21 is carefully designed to match the output impedance of the sensors, ensuring efficient signal transfer. For example, when receiving a 4 - 20 mA current signal, the input impedance of the Pgs21 is typically high enough to minimize the impact on the sensor's output and ensure accurate signal measurement.
Output Signal: Once the input signal is received, the Pgs21 accurately repeats the signal at the output terminals. The output signal is also in a standard format, such as 4 - 20 mA, which can be easily connected to the control system. The output signal has a high degree of accuracy and stability, with a low level of noise and distortion. The Pgs21 is capable of driving loads up to a certain value, ensuring that the signal can be transmitted over long distances without significant degradation. For instance, it can drive loads of up to [load value in ohms] while maintaining the integrity of the output signal.
Galvanic Isolation: Galvanic isolation is a key feature of the Pgs21. 

2. Technical Specifications

2.1 Supply
Connection: The power supply for the Pgs21 can be connected through dedicated terminals. The connection is designed to be secure and easy to make, ensuring a reliable power supply to the device. The terminals are clearly marked, making it convenient for technicians to connect the power cables.
Rated Voltage: It operates on a rated voltage range of [voltage range in V DC or V AC]. For example, it may be designed to operate on a 24 V DC power supply with a tolerance of ± [tolerance percentage]. This wide voltage range allows the Pgs21 to be used in different industrial settings, where the available power supply may vary.
Rated Current: The rated current consumption of the Pgs21 is relatively low, typically ≤ [current value in mA]. This low power consumption is beneficial as it helps in reducing the overall power requirements of the industrial system. It also makes the Pgs21 suitable for use in battery - powered or energy - sensitive applications.
Power Dissipation: The power dissipation of the Pgs21 is ≤ [power value in mW]. This indicates the amount of power that is dissipated as heat during the operation of the device. The low power dissipation helps in maintaining the device's temperature within a safe operating range, even in continuous operation.
2.2 Input
Connection: The input is connected on the field side through terminals that are designed to accept different types of sensor connections. The terminals are made of high - quality materials to ensure a reliable electrical connection. They are also designed to be resistant to corrosion, which is important in industrial environments where the device may be exposed to harsh chemicals.
Input Signal Types: As mentioned earlier, the Pgs21 can handle various input signal types, including 4 - 20 mA current signals and voltage signals. The voltage input range may be, for example, [voltage input range in V]. The device is also capable of handling other types of signals, such as resistance - temperature detector (RTD) signals and thermocouple signals, with the appropriate signal conditioning modules.

3.Applications

3.1 Oil and Gas Industry
Wellhead Control: In oil and gas wellheads, the Pgs21 is used to control the opening and closing of valves that regulate the flow of oil and gas. By providing a safe and reliable signal transmission to the valve positioners in the hazardous wellhead area, it ensures the proper operation of the well and prevents potential leaks and explosions. The Pgs21's ability to handle harsh environmental conditions, such as high temperatures and exposure to oil and gas vapors, makes it an ideal choice for wellhead applications.
Pipeline Pump Stations: At pipeline pump stations, the device is used to control the speed and operation of pumps. The accurate signal repetition and intrinsic safety features of the Pgs21 are crucial for maintaining the smooth flow of oil and gas through the pipelines and for ensuring the safety of the personnel and equipment in the potentially explosive environment of the pump station. The Pgs21 can also be used to monitor the pressure and flow rate of the pipelines, providing real - time data to the control room for better process control.
