HART protocol

1. HART is a hybrid analog + digital protocol. It superimposes an FSK digital signal onto a traditional 4-20mA two-wire current loop, with both utilizing

2. -20mA is a DC analog signal; HART is a 1200/2200Hz AC FSK digital signal superimposed on top. The AC average is 0, so they do not interfere with each other. A typical PLC 4-20mA analog input card can only read the DC 4-20mA signal and cannot read the HART digital parameters, directly filtering out the high-frequency HART signal as noise.

3. HART requires signal conversion via a HART modem. Wiring: Connect in parallel across the two ends of the 4-20mA loop, regardless of positive or negative. It does not need to be connected in series and will not affect normal PLC communication.

The workstation's four regulation segments can operate independently.

Compact didactic station for instrumentation, automation, and process control exercises, designed for the study of industrial variables in recirculation and regulation systems.

Didactic content:

Regulation of at least four process variables: level, flow rate, pressure, and temperature.
Each variable must be capable of independent operation.
Capability for cascade control exercises, particularly between level and flow rate.
Upper tank, lower reservoir, pressurized tank for fluid recirculation.
Pump for continuous operation. The unit feature an intelligent water circulation.
Flow rate regulation via pump speed variation, proportional valve, valve with positioner, final control element.
2-way ball valve with pneumatic actuator system for generating controlled disturbances.
Configurable didactic sensors for process measurement.
Capacitive level sensor (dual-rod probe type):
