伽马测量仪使用“镅”作为恒发射源,这一发射源位于“C”框架组装的较低部。结构的**部是一个接收器和前置放大器。当通过发射源和接收器之间的间隔时,金属带会吸收一部分辐射,吸收量视其厚度和密度而定。剩下的一部分就由接收器进行测量,并转化成带厚度测量。 为了节省时间和费用,公司先试着在已有的PLC系统中进行高级模拟测量和处理。但是,PLC的模拟I/O和信号处理无法达到所需的精确度。I2S公司要确保运行于PLC中的控制系统不会因为额外I/O和处理的增加而减少。 因此,他们需要这么一个系统,这个系统能够从伽马传感器中获取模拟信号并进行处理以计算精确的厚度测量值,并能将这个厚度测量插入到PLC控制系统中。但是,所用的PLC不适合高性能处理和高速模拟I/O。5069-OF8 5069 Compact I/O 8 Channel Voltage/Current Analog Output Module 5069-IB8S Compact 5000 8 Channel 24VDC Safety Input Module 5069-IB8SK Compact 5000 8 Channel 24VDC Safety Input Module - Conformally Coated 5069-IB16K 5069 Compact I/O 16 Channel 24V DC Sink Input Module,Conformal Coated 5069-IA16 5069 Compact I/O 16 channels AC input modules, supporting both 120 & 240 VAC **s 5069-IB16 5069 Compact I/O 16 Channel 24V DC Sink Input Module 5069-IB16F 5069 Compact I/O 16 Channel Fast 24V DC Sink Input Module 5069-IB6F-3W 5069 Compact I/O 6 Channel 3 Wire Fast 24V DC Sink Input Module 5069-OA16 5069 Compact I/O 16 channels AC output module supporting both 120 & 240VAC output. 5069-OB8 5069 Compact I/O 8 channels high current 2A discrete output. 5069-OBV8S Compact 5000 8 Channel 24VDC Safety Configurable Output Module 5069-OBV8SK Compact 5000 8 Channel 24VDC Safety Configurable Output Module - Conformally Coated 5069-OB16 5069 Compact I/O 16 Channel 24V DC Source Output Module 5069-OB16F 5069 Compact I/O 16 Channel Fast 24V DC Source Output Module 5069-OB16K 5069 Compact I/O 16 Channel 24V DC Source Output Module,Conformal Coated 5069-IY4K 5069 Compact I/O 4 Channel Universal Voltage/Current/RTD/TC Analog Input Module,Conformal Coated 5069-OF4K 5069 Compact I/O 4 Channel Voltage/Current Analog Output Module,,Conformal Coated 5069-OW4I 5069 Compact I/O 4 Channel Normally open individually isolated type Relay Output Module 5069-OW16 5069 Compact I/O 16 channels non isolated normally open relay output module. 5069-OX4I 5069 Compact I/O 4 Channel Normally open/Normally Closed individually isolated type Relay Output Module 5069-FPD 5069 Compact I/O Field Potential Distributor Module 5069-HSC2XOB4 5069 Compact I/O 2 Channel High Speed Counter Module with 4 Channel 24V DC Source Outputs 5069-ARM 5069 Compact I/O Address Reserve Module 5069-STRT10 5380 Experience Kit containing 5069-L306ERM, 5069-IB16F, 5069-OB16, Ethernet Cable, USB cable and 2080 power supply 5069-L306ER Controller, CompactLogix 5380, 600 KB User Memory, 8 I/Os, 16 EtherNet/IP Devices 5069-L310ER Controller, CompactLogix 5380, 1 MB User Memory, 8 I/Os, 24 EtherNet/IP Devices 5069-L320ER Controller, CompactLogix 5380, 2 MB, 16 I/Os, 40 EtherNet/IP Devices 5069-L330ER Controller, CompactLogix 5380, 3 MB User Memory, 31 I/Os, 60 EtherNet/IP Devices 5069-L340ER Controller, CompactLogix 5380, 4 MB User Memory, 31 I/Os, 90 EtherNet/IP Devices 5069-L310ER-NSE Controller, CompactLogix 5380, 1 MB User Memory, 8 I/Os, 24 EtherNet/IP Devices, No Super Cap 5069-L306ERM Controller, CompactLogix 5380, 600 KB User Memory, 8 I/Os, 2 axis, 16 EtherNet/IP Devices 5069-L310ERM Controller, CompactLogix 5380, 1 MB User Memory, 8 I/Os, 4 axis, 24 EtherNet/IP Devices
