Plugged Impulse Line Detection (PILD)
An advanced diagnostic function Plugged Impulse Line Detection (PILD) becomes available in
ST800 SmartLine Pressure Transmitters (R300.3) in Differential Pressure (DP) transmitters,
Absolution Pressure (AP) transmitters and Gauge Pressure (GP) transmitters.
PILD is a powerful tool to detect when the impulse lines are blocked by solids or frozen fluid in
process. Alarms on impulse line blockage will allow users to take proper measures at an early point of
time so that effect of false readings from transmitters on process control can be minimized. See
HART transmitter parameters, Table 11 on page 33 .
Install Date
Date of device installation. Date displayed in mm/dd/yyyy
format where mm=month, dd=day, yyyy=year
User enters a date once during device lifetime. Once
date is entered no further updates are possible and value
becomes read only and is permanently saved.
