Technical overview

The µP-regulated, programmable
pressure transmitter type 619 has a
robust industry design. Parameters
can easily be programmed with
three different configuration me­nus.

All systems are equipped with a
diagnostic function. Pressure is
measured by a high resistante ce­ramic element. Normed analogue­and / or open collector outputs are
available depending on the version
chosen.

Outputs

0 – 10 V
4 – 20 mA
Open-collector switching output for

max. 200 mA, programmable NPN
or PNP,

Contact NO or contact NC
Short circuit proof, and protected

against polarity reversal. Each
connection against other with max.
+/– supply voltage.

Load

0 – 10 V > 10 kOhm
4 – 20 mA < 500 Ohm

Current consumption

typ. 50 mA, max. 200 mA

Electrical connection

M 12, Snap-C compatible,
4 contact pins

Admission

Displays

7 Segment LED, 4 digits for the
indication of

• pressure measuring values

• programming codes

• parameter values

• reaction time
Point-LED for state indication of
switching points
Point-LED for indication of pro­grammed measuring unit

Programming

All settings can made in unpressur­ized state or during the operation.
Ex works with standard setting. The
diagnostic function is active in all
menus.

Menus: «PROG» Configuration of
different system functions, input of
switching point, diagnostic function
«USER» Input of switching point
«READ» Reading of all configuration­and input parameters

Display: Pressure unit in bar/psi or
MPa/psi. Reaction time elegible in
steps 1% fs (slow), 0.5% fs (normal) or
10 ms (fast).

Analogue output: Response time
adjustable of 5 … 500 ms, output
characteristic line adjustable of
75 … 125% fs

Digital output: Measuring range
rising pressure 8 … 100% fs
falling pressure 5 … 97% fs
P or N-switching, open-close­contact, rise-delay time eligible
Rise-delay time 0 – 50 s
Switch off delay time 0 – 50 s
Response time 5 … 500 ms

• Robust industry design

• High over pressure

• 4-digit LED display

• Sensitive operation keys

• Ergonomic design

• Diagnostic function

• Front cover
