Deltabar PMD75B PROFINET with Ethernet-APL Technical data
Endress+Hauser 79
15 Technical data
15.1 Output
Output signal PROFINET with Ethernet-APL
10BASE-T1L, 2-wire 10 Mbit
Signal on alarm Signal on alarm in accordance with NAMUR recommendation NE 43.
PROFINET with Ethernet-APL:
• According to "Application Layer protocol for decentralized periphery", Version 2.4
• Device diagnostics according to PROFINET PA Profile 4.02
Damping A damping affects all outputs (output signal, display). Damping can be enabled as follows:
• Via the onsite display, Bluetooth, handheld terminal or PC with operating program,
continuous from 0 to 999 seconds
• Factory setting: 1 s
Ex connection data See the separate technical documentation (Safety Instructions (XA)) on
www.endress.com/download.
Linearization The device's linearization function allows the user to convert the measured value to any
units of height or volume. User-defined linearization tables of up to 32 value pairs can be
entered if necessary.
Flow measurement with
Deltabar and differential
pressure sensor
Low flow cut off parameter: When the Low flow cut off parameter is activated, small
flows which can lead to large fluctuations in the measured value are suppressed.
The Low flow cut off parameter is set to 5% by default when the Output current transfer
function parameter is set to Square root option.
