E+H Company, founded in 1953 by Swiss engineer Georg H. Endress and German banker Ludwig Hauser, is headquartered in Reinach, Switzerland, located at the border of Germany, Switzerland, and France. It has established large-scale production centers in industrialized countries such as Germany, Switzerland, France, the United States, Japan, and China, with 6077 employees and 70 independent subsidiaries. Its strict quality management and complete quality assurance system have reached ISO9001 standards. In 2006, sales reached 1 billion euros.
Convert the pressure magnitude into a standardized unified signal, such as 4-20mA DC, to represent it. For example, converting a pressure of 0-10MPa into a direct current of 4-20mA, then connecting an ammeter through a wire, and dividing the corresponding position of the 4-20mA scale of the ammeter into 10 equal parts, marking the word 0-10MPa, can read the pressure value from a far distance.
E+H is the name of a manufacturer of control equipment.
The E+H pressure transmitter has gained a high market share due to its good performance and relatively affordable price. Therefore, although the quality of the E+H pressure transmitter is relatively stable, there may still be some small problems after a long period of use. In order to avoid these problems, I have summarized some knowledge about the price of pressure transmitters. For example, the price of pressure transmitters may vary slightly in different places, and the purchasing location is of course our company. The following information is hoped to be helpful to customers.
1. The on-site environment of the equipment is relatively harsh, and strong electrical signals can generate various electromagnetic interferences. Lightning induction can produce strong surge pulses. In this situation, a tricky problem encountered in microcontroller application systems is how to reliably transmit small signals over long distances in harsh environments
Considering that the high-frequency noise of the E+H pressure transmitter passes through the transformer mainly not through the mutual inductance coupling of the primary and secondary coils, but through the parasitic capacitance coupling of the primary and secondary coils, a shielding layer is used to isolate the primary and secondary of the isolation transformer, reducing its distributed capacitance and improving its resistance to common mode forces.
2. However, the price of E+H pressure transmitters is limited in situations where signals need to be transmitted over long distances or there is significant interference from the power grid. The use of voltage output sensors is restricted, exposing disadvantages such as poor resistance, line losses that damage accuracy, etc. The two-wire current output transmitter has been widely used due to its excellent resistance.
The magnitude of the potential difference depends on the concentration of antimony trioxide, which corresponds to the moderate concentration of hydrogen ions in the acidic solution being measured. If the appropriate values of antimony, antimony trioxide, and aqueous solution are all taken as 1, their electrode potentials can be calculated using the Nernst formula.
The concentration of an acid-base solution is proportional to its conductivity. Therefore, as long as the conductivity of the solution is measured, the level of acid-base concentration can be determined. When the measured solution flows into the conductivity cell, if electrode polarization and distributed capacitance are ignored, it can be equivalent to a pure resistance. When a constant voltage alternating current flows through, the output current is linearly related to the conductivity, which is proportional to the concentration of acid and alkali in the solution. Therefore, as long as the solution current is measured, the concentrations of acid, alkali, and salt can be calculated.
4. This type of malfunction requires replacement of the amplifier board. The requirements for circuit design and process assembly quality of transmitters are very strict. In actual use, for any circuit faults that occur, after inspection and confirmation, the faulty circuit board will be replaced with the manufacturer to ensure the stability of instrument operation and reliable price of pressure transmitters.
5. The influence of installation position of E+H micro differential pressure transmitter on zero position output. Due to its small measurement range, the self weight of the sensing element in the transmitter will affect the output of the micro differential pressure transmitter. Therefore, the zero position change that occurs during the installation of the micro differential pressure transmitter is normal. During installation, the axial direction of the pressure sensitive part of the transmitter shall be perpendicular to the gravity direction. If the installation conditions are limited, the zero position of the transmitter shall be adjusted to the standard value after installation and fixation.
When the pressure on both sides of the transmitter is different, the working principle of the pressure transmitter and the pressure transmitter is the same as that of the differential pressure transmitter, except that the pressure in the low-pressure chamber is atmospheric pressure or vacuum.
7. We know that regardless of the model of differential pressure transmitter, both the positive and negative pressure chambers have exhaust valves, drain valves, or plugs; This provides convenience for us to calibrate the differential pressure transmitter on site, which means that the differential pressure transmitter can be calibrated without removing the pressure pipe. For this purpose, DLR has processed and produced joints with the same thread as exhaust, drain valves, or plugs.
8. Thermistor is a primary component that converts temperature changes into changes in resistance values, usually requiring the resistance signal to be transmitted to a computer control device or other primary instrument through leads. Industrial thermal resistors are installed on the production site and have a certain distance from the control room, so the leads of the thermal resistors will have a significant impact on the price of pressure transmitters.
A 9-resistor strain gauge is a sensitive device that converts strain changes on the measured component into an electrical signal. It is one of the main components of a piezoresistive strain transmitter. The most commonly used types of resistance strain gauges are metal resistance strain gauges and semiconductor strain gauges. There are two types of metal resistance strain gauges: wire strain gauges and metal foil strain gauges. Usually, strain gauges are tightly adhered to a mechanically strained substrate using a special adhesive. When the substrate undergoes stress changes, the resistance strain gauges also deform, causing a change in the resistance value of the strain gauges and a change in the voltage applied to the resistance.
