Wireless will advance but never rule
无线——技术进步而非完全取代

There was a time when pneumatics technicians said, “I’ll never allow those 4-20 mA to run in this plant.”
曾经有段时间，气动技术员说：“我决不允许这些4-20mA信号在这家工厂运行。”

There was a time when analog instrumentation people said, “We’ll never run that digital stuff on these wires.”
又曾几何时，模拟仪器员说：“我们绝不能在电缆接线上传送数字东西。”

Now, and despite the promise from the ISA100 developers the new wireless standard will ensure that automation wireless signaling will be more reliable than hardwire digital transmission, the same refrain echoes. There’s still distrust for the technology.
现在，尽管开发者承诺新的ISA100无线标准，将确保自动化无线信号会比电缆硬接线数字传输更为可靠，但是反对的声音仍回响在空中（又跳了出来），对新技术不信任的传统仍在延续。

“We won’t be using wireless for critical control applications at our plant anytime soon,” said Jim Albert, a process engineer at Allston, Mass-based Genzyme Corp. “We’re just not comfortable with that.”
“我们不会马上在工厂的关键控制应用上使用无线技术 ”吉姆艾伯特，一个来自奥斯顿，Mass-based Genzyme公司的工艺工程师， “我们只是觉得不放心。”

Albert had just received a wireless innovator’s award for his wireless application at the Emerson Global Users Exchange at National Harbor, Md. when he made this comment to the trade press.
在华盛顿国家港湾区举行的爱默生全球用户交流会上，艾伯特因为其对无线的应用，刚刚获得一项无线革新者奖，他对行业媒体发表了上述评论。

His award was for the wireless monitoring of the temperature in vessels containing nitrogen. Genzyme is a biotechnology company that produces enzymes for treating rare diseases. Their customers and patients reside in 90 countries around the world.
这个奖项用于表彰其在氮容器温度无线监控方面的应用。Genzyme是一家生物技术公司，它生产的酶用于治疗罕见疾病。其客户和患者分布于全世界90余个国家。

Indeed, John Berra, chairman of Emerson Process Management, touted the coming of wireless during his keynote speech earlier this week. WirelessHART is probably the crown jewel of his legacy.
事实上，爱默生过程控制有限公司的主席John Berra，在本星期早些时候的主题演讲中极力吹捧无线时代的到来。 WirelessHART可能是他离任遗产中“皇冠上的明珠”。

Berra predicts wireless will handle 20% of the measurements in plants and factories some day. “It’s a huge market,” he said.
Berra预测，某一天，无线技术将担当处理工厂中20％的测量任务。他说，“这是一个巨大的市场”。

In fact, there are analyst predictions that say the number is double that – 40%.
事实上，有分析师预测说，这个数字将会达到两倍—4 0％ 。
