Effect of Lead Wire Resistance on RTD
RTDs generally use copper leads bonded to the platinum element. These leads normally connect close to the element and close

Control valves are available in different types and shapes. They can be classified in different ways; based on: (a) action,
PLC outputs are of two types: 1. Relay. 2. Solid state. Relay outputs are mechanical contacts and Solid State outputs are like transistor, TRIAC.
There are two primary system considerations centering around an emergency operational situation for control valves. Control Valve Fail Safe Action
The term “earth resistivity” expressed in ohm-centimeters (abbreviated ohm-cm) is one basic variable affecting resistance to earth of an electrode
Installation of a Control Valve When installing a control valve, please observe the following: Before installation, ensure that scales, welding
Piping and Instrumentation Diagram (P&ID) is a drawing elaborating the details of piping and instrumentation of a processing plant, developed
Process Flow Diagram (PFD) is a drawing which essentially captures the process flow for a processing plant. PFD is used
This section covers the PLC Analog I/O Potential Problems and PLC troubleshooting tips for the basic programmable logic controller (PLC).
The Oil in Water Analyzer uses the UV source, photo-detector, and a sample cell to measure the fluorescence light.
