What is SPB capacitive intelligent differential pressure-pressure transmitter
The SPB capacitive intelligent differential pressure-pressure transmitter uses a capacitive sensing element to measure the pressure difference. The sensing element consists of two parallel plates that are separated by a small gap. When pressure is applied to the plates, the distance between them changes, which results in a change in capacitance. This change in capacitance is then converted into an electrical signal that can be used to determine the differential pressure.
Types of SPB capacitive intelligent differential pressure-pressure transmitter
1.Absolute Pressure Transmitter: This type of transmitter measures the differential pressure between a vacuum and a known pressure. It is commonly used in applications where the reference pressure is known and fixed, such as in vacuum systems or barometric pressure measurements.
2.Gauge Pressure Transmitter: This type of transmitter measures the differential pressure between the process pressure and the atmospheric pressure. It is commonly used in applications such as tank level monitoring, HVAC systems, and compressed air systems.
3.Differential Pressure Transmitter: This type of transmitter measures the difference in pressure between two points in a system. It is commonly used in applications such as flow measurement, filter monitoring, and pump performance monitoring.
Advantages of SPB capacitive intelligent differential pressure-pressure transmitter
1.High Accuracy: The capacitive sensing element used in these transmitters provides high accuracy, even at low pressure differentials.
2.Wide Range of Pressure Measurement: These transmitters are capable of measuring a wide range of differential pressures, from very low to very high pressures, depending on the specific model.
3.Durability: These transmitters are designed to operate in harsh environments and can withstand extreme temperatures, pressures, and vibrations.
