2.1 Probes and sensors
Table 2.1 lists the sensors most frequently used with the Prolevel FMC 661 transmitter.
In addition to those listed, all probes which can be used with an EC 17 Z, EC 37 Z or
EC 47 Z electronic insert can be connected to the transmitter. Installation hints can be
taken from the appropriate Technical Information Sheet.
Sensor constantsDeltapilot S hydrostatic pressure sensors and EC 37 Z/47 Z inserts are supplied with the
sensor constants zero frequency »fo« and sensitivity »∆f« or »S«, see Fig. 2.2. For
Deltapilot S sensors the constants depend on the measuring range, see Table 2.2. Note
these constants and enter them into fields V3H5 and V3H6 during commissioning,
Section 4.1. This dispenses with the need for a recalibration of the transmitter on
replacement of the sensor or insert.
