1151 series intelligent capacitive transmitter (hereinafter referred to as smart transmitter) is a microprocessor-based pressure meter, it is in the traditional structure of the 1151 capacitive transmitter increased communication and other.Communicator or Other hosts using the HART protocol can communicate bidirectionally (read, write data and diagnostics) in the control room, at the transmitter site, or anywhere in the same control loop.

1, the main features

1151 series intelligent capacitive transmitter in addition to the inherent characteristics of the general capacitive transmitter, but also has the following characteristics:
• Intelligent electronic components consist of only one piece
• Span ratio 15: 1 or 10: 1
· 0-0.6-0-42000KPa
• Local buttons adjust the range and zero
· Can update the existing SAI-1151 (including 1151) a variety of analog transmitter for the smart meter
· Conforms to the HART agreement, may use the HART communicator to carry on two-way communication with this intelligence table without interrupts the output signal
• Two-way communication with the host in a decentralized control system using HART protocol
· With self-diagnosis and remote diagnosis
With EEPROM, not afraid of power loss data

2, the working principle

Two kinds of pressure of the measured medium pass into the high and low two pressure chambers, acting on the two sides of the delta element (ie, the sensing element) on the diaphragm, through the separator and the filling liquid in the element to the measuring diaphragm. Measuring diaphragm and the two sides of the insulating film on the electrode to form a capacitor.When the pressure on both sides of the inconsistency, resulting in displacement measurement diaphragm, the displacement and the pressure difference is proportional to the capacitance on both sides of the range, through the oscillation and Demodulator, and converts it into a signal proportional to the pressure The transmitter and the absolute pressure transmitter operate in the same way as the differential pressure transmitter, except that the low pressure chamber is atmospheric or vacuum. Adjust the current into a digital signal, the value of the microprocessor is used to determine the input pressure value.Microprocessor control transmitter work.In addition, it is linear sensor.Return the measuring range. Engineering unit conversion, damping, Square root, sensor trim and other operations, as well as diagnostics and digital communications.
The use of objects: liquid, gas and steam.
