產(chǎn)品詳情：TMU4交通軸信號處理器
The HI-TRAC? TMU4 is a high speed trafficdata collection system recording vehicle classifiation and axle load data without interruption to traffi flow.The HI-TRAC? TMU4 incorporates embedded Ethernet with TCP/IP stack, VPN and FTP as well as extensive 8 Gb data storage and thus provides high-end functionality at a reasonable cost.The standard configurationof two Class 1 piezo electric sensors and one inductive loop installed in the highway per lane provides axle weight data to COST 323 Class B(10) accuracy in addition to inter-axle spacing and vehicle speed data.The system can be used as a statistical data device to record highway trafficloading or it can also be used as a screening weighbridge to identify overloaded vehicles in the traffic steam.The HI-TRAC? TMU4 can be interfaced to trafficsignals or diversion signs to intercept overloaded vehicles and to ANPR or CCTV camera systems.The HI-TRAC? TMU4 uses TDC Systems advanced loop profilig techniques to improve vehicle classificationaccuracy and weight data is significantl improved with advanced automatic temperature compensation algorithms incorporated as standard.

管道液位傳感器應(yīng)用領(lǐng)域
管道液位傳感器是一種利用光學(xué)原理來檢測水管液位的傳感器，其工作原理基于光線在水和空氣中折射率不同的特性。通過光電管道傳感器，可以有效解決傳統(tǒng)機(jī)械式傳感器存在的低精度、卡死失效等問題，同時(shí)也避免了電容式傳感器因感度衰減而導(dǎo)致的不可控性失效。利用紅外光學(xué)組件，通過巧妙的設(shè)計(jì)形成感應(yīng)線路，能夠快速、
