CONSIDERATIONS General Electrical temperature sensors such as RTDs and thermocouples produce low-level signals proportional to their sensed temperature. The Models 244EH and 244ER transmitters convert the low-level sensor signal to a standard 4–20 mA dc signal that is relatively insensitive to lead length and electrical noise. This current signal is then transmitted to the control room via two wires. Mechanical When choosing an installation location and position, take into account the need

Multichannel Installations Several transmitters can be connected to a single master power supply as shown in Figure 2-9. In this case, the system may be grounded only at the negative power supply terminal. In multichannel installations where several transmitters depend on one power supply and the loss of all transmitters would cause operational problems, consider a back-up battery or power supply that cannot be interrupted. The diodes shown in Figure 2-9 prevent unwanted charging or discha
