Reliability Sensor check system (SCS (Plus package)) The Sensor Check System (SCS) monitors the high impedance of the pH glass. An alarm is issued if a minimum impedance value is undershot or a maximum impedance is exceeded.
- Glass breakage is the main reason for a drop in high impedance values
- The reasons for increasing impedance values include: – Dry sensor – Worn pH glass membrane Sensor live check (process check system, PCS (Plus package)) The process check system (PCS) checks the measuring signal for stagnation. An alarm is triggered if the measuring signal does not change over a specific period (several measured values). The main causes of stagnating measured values are:
- Contaminated sensor, or sensor outside of medium
- Sensor defective
- Process error (e.g. through control system) Plausibility check pH electrodes are usually always calibrated with the same pH values. The transmitter therefore provides the setting for the last calibration as a default value when the next calibration is performed. If the buffer solutions are swapped by mistake during the calibration (e.g. pH 4 buffer first, then pH 7 buffer instead of pH 7 buffer first, then pH 4 buffer), the plausibility check ensures that the calibration is accepted nevertheless. Current output configuration (Plus package) In order to display wide measuring ranges while still achieving a high resolution in specific ranges, the current output can be configured as required via a table. This permits bilinear and quasi- logarithmic curves etc. Current input The transmitter current input permits two different applications:
- Flow monitoring with controller switch-off if flow falls below lower flow level in the main flow
- Feedforward control to the controller The two functions can also be combined. Neutralization controller (Plus package) The neutralization of solutions requires a special control response which cannot be provided satisfactorily with a simple P(ID) response. The transmitter provides the control response of a special neutralization controller combined with two P(ID) controllers. Safety Process safety Different alarms are required depending on the application and operator. The transmitter therefore permits the independent configuration of the fault-signaling contact and the error current for every individual error. Unnecessary or undesired alarms can be suppressed in this way. Up to four contacts can be used as limit contacts (also for temperature), as a P(ID) controller and for cleaning functions. The direct manual operation of the contacts (bypassing the menu) enables quick access to limit value, control or cleaning contacts. Any deviations can be quickly corrected in this way.
