CAUTION
PRODUCT DAMAGE DUE TO MECHANICAL ISSUES
• Ensure torque specifications are determined for the specific application. Values provided are for reference only. (Mating
materials and thread sealants can result in significantly different torque values from one application to the next.)
• When using mating parts made of stainless steel, use a thread sealant with anti-seize properties to prevent thread galling.
Ensure the sealant is rated for the application.
• Use appropriate tools (such as an open ended wrench or deep well socket) to install transducers.
• Always hand-start transducers into the hole to prevent cross threading and damage.
• Ensure that torque is not applied to the electrical connector.
• Ensure that the proper mating electrical connector with a seal is used to connect the transducer. Improper or damaged
seals can compromise ingress protection, leading to short circuits.
Failure to comply with these instructions may result in product damage.
CAUTION
PRODUCT DAMAGE DUE TO PARTICULATES
• Ensure that a filter is used upstream of the transducer to keep media flow free of larger particulates and increased humidity.
All MLH Series transducers are dead-ended devices; particulate accumulation and condensing moisture may affect
transducer output.
• It is recommend that the transducer be positioned with the port facing downwards; any particulates in the system are less
likely to enter and settle within the pressure transducer if it is in this position.
• Ensure that the media does not create a residue when dried. Build-up inside the transducer may affect transducer output;
rinsing of a dead-ended transducer is potentially difficult and has limited effectiveness in removing residue.
Failure to comply with these instructions may result in product damage.

C++ 属于面向对象的编程语言，OOP的思想不必多说，特别对于复杂的软件工程来说，利用OOP绝对是事半功倍，相对于传统的C来说； 当然用C来写单片机程序无可厚非，已经延续了一个传统，从大学时学的开始到工作岗位，好多人都是一直用C来做，但是既然Keil支持C++编译， 可以用C++来编写你的代码，可以利用高级语言来结构化，清晰化你的程序，为嘛不用呢！哈哈，个人看法！下面进入正题： C+...[详细]
