6, choose what kind of excitation voltage: type of the output signal is determined how to choose the excitation voltage. Many amplification transmitter has a built-in voltage regulator, able to get a job to decide whether to use sensors with voltage regulator, to consider the operating voltage and system cost when selecting transmitter. 7, the need to have interchangeability of transmitters: to determine whether the required transmitter can accommodate multiple use systems. Generally speaking, this is very important. Especially for OEM products, once the products to the customer, then the customer is used to calibrate spending is quite large. If the product has a good interchangeability, even if it is used to change the transmitter Honeywell handheld terminal, it will not affect the results of the entire system. High-performance SmartLine Guided Wave Radar Level Transmitter with industry-leading technology standards Honeywell HART specification, can provide users with the best experience of application testing. Which line inspection tool using Honeywell Communicator, users can enter specific reservoir technical data to verify the correct application level transmitter, which can be delivered smoothly to on-site installation of the box. Honeywell process control field vice president and general manager of product business unit Ma Fun (DonManess) said: "The new level transmitters based on Honeywell's proven SmartLine platform, innovative modular design and ease of use with the same series of pressure and temperature transmitters, as this will help to reduce the amount of inventory storage, faster boot time, so as to better manage costs costs. users can also use our application testing tools to ensure their custom solution position transmitter fully meet the needs filling applications.
