HART intelligent transmitter continuously compares main
variable value with the upper and lower limit value. When main
variable value exceeds the upper and lower limit, the module
outputs fixed current, indicating that the main variable exceeds the
range. When the main variable is higher than the upper limit, the
output is fixed at 20.8 mA. When it’s lower than the lower limit, the
output is fixed at 3.8 mA.
