Product introduction:
Model: D520M/7DD
Name: Ex-Proof DP controller
Manufacturer: Shanghai Automation Instrumentation Co., Ltd.
Application: D520M/7DD Ex-Proof DP controller
Description of 0818680 D520M/7DDP Ex-proof DP controller 1-10KPa:
The 0818680 D520M/7DDP Ex-proof DP controller 1-10KPa uses a diaphragm type sensor whose explosion-proof rating is de II CT5, which can be used in the air, suchas general gas medium and water, oil and other liquid medium. The setting value of the controller is adjustable, and the range of adjustment is 0...... 25kPa.
Parameters of 0818680 D520M/7DDP Ex-proof DP controller 1-10KPa:
Viscosity: < 1 * 103m2/s
Explosion proof grade: Exde II CT5
Repeatability error: less than 2%
Ambient temperature: 0~55 DEG C
Medium temperature: stable operating temperature of 0~60degrees, short-term operating temperature of 95 degrees. If the temperatureabove is exceeded, a long enough coolant pipe (3 meters or more) and a bufferfitted in front of the controller shall be provided. When the medium is cooledto the required temperature before the buffer, the high and low pressure stopvalves in the buffer can be opened.
Installation position: the cover plate with glass plate shouldbe vertical to the horizontal direction. At the same time, the diaphragm isperpendicular to the surface.
Vibration resistance: Max: 20m/s2
Enclosure protection level: IP54
Contact capacity: DC, 250V, 0.25A (resistance) 60Wmax
AC, 250V, 5A (resistive) 1250Vamax
