VII. FAQ

Q1: What is the difference between 266DRH and 266DSH?

A: The 266DRH is a differential pressure transmitter with remote diaphragm seal, measuring process pressure indirectly through capillary tubes and remote diaphragms, suitable for harsh conditions such as high temperature, high viscosity, easy crystallization, and strong corrosivity; the 266DSH is a direct mounted differential pressure transmitter, with process media directly contacting the sensor diaphragm, suitable for general conditions. Both have base accuracy of ±0.06%, the main difference is whether they are equipped with a remote diaphragm seal system.

Q2: What is the accuracy of this transmitter?

A: The base accuracy of the 266DRH series differential pressure transmitter is ±0.06% (percentage of calibrated span), with a turndown ratio of up to 60:1, meaning it maintains high-precision measurement within a 60:1 span range. This is the performance level of ABB high-end pressure transmitters, suitable for process control applications requiring high measurement accuracy.

Q3: What is the function of the remote diaphragm seal?

A: The remote diaphragm seal system transmits process pressure from the diaphragm mounted on the process piping to the transmitter sensor through capillary tubes. Its main functions include: ①Isolating process media from the sensor, protecting the sensor from high temperature, corrosion, crystallization, etc.; ②Solving high temperature media measurement problems (capillary tubes and seal fluid can withstand high temperatures); ③Facilitating maintenance, the transmitter can be installed away from the process piping; ④Suitable for measurement of high viscosity, easy crystallization, easy solidification media, avoiding impulse line blockage.

Q4: Can you provide detailed configuration and selection support for this transmitter?

A: Yes. Please contact via email with your application conditions, including measurement media, process temperature, process pressure, differential pressure range, process connection method, explosion-proof requirements, communication protocol, etc. We will provide corresponding detailed configuration analysis, selection recommendations, installation guides and technical support.
