Sensor boxes SRBE

Key features and product range overview

Function

Sensor boxes SRBE are used for electrical feedback and control of the position of process valves actuated using pneumatic quarter turn actuators. They are suit able for use in potentially explosive environments. They can be mounted quickly

Innovative Flexible Design

 Pre-assembled mounting adapter

for ease of installation

 The trip cams can be set easily

without additional tools

 Sturdy, corrosion-resistant design,

ideal for use in harsh operating conditions

 Clearly visible 3D position indicator

allows rapid detection of the current position of the quarter turn actuator

 Worldwide certifications (ATEX,

IECEX, cCSAus, INMETRO) for use in potentially explosive environments

 The type of protection of the

flameproof enclosure enables installation without safety barriers or NAMUR amplifier in potentially explosive environments

 Weather-tight housing for outdoor

applications too

 Mechanical, inductive or magnetic

switch variants for virtually all ranges of application

 Two cable inputs for common power

supply for the sensor box and solenoid valve as standard

and easily on quarter turn actuators with a connection pattern to VDI/VDE 3845 using mounting adapters.

 Sturdy aluminium housing with two

cable inputs

 Captive stainless steel screws on

the housing cover

 Pre-assembled stainless steel

mounting adapter 80x30 H20 for ease of mounting on standard actuators to VDI/VDE 3845

 3D OPEN/CLOSED position indic

ator

 Mechanical, inductive or magnetic

switch variants

 Number of switches: 2  IP67, NEMA 4/4x  ATEX, IECEX, cCSAus, INMETRO  SIL 2 to IEC 61508
