Product Description

Type 3730-3 Electropneumatic Positioner
The positioner ensures a predetermined assignment of the valve position (controlled variable x) to the input signal (set point w). It compares the input signal received from a control system to the travel or rotational angle of the control valve and issues a corresponding output signal pressure (output variable y).
Specification
Special features 
• Simple attachment to all common linear and rotary actuators – SAMSON direct attachment (Fig. 1) – NAMUR rib (Fig. 2) – Attachment to rod-type yokes acc. to IEC 60534-6-1 – Attachment according to VDI/VDE 3847 
– Rotary actuator attachment according to VDI/ VDE 3845 (Fig. 3) 
• Any desired mounting position of the positioner (but not suspended) 
• Simple single-knob, menu-driven operation 
• LCD easy to read in any mounted position due to selectab
le reading direction 
• Configurable with a PC over the SSP interface using the 
TROVIS-VIEW software 
• Variable, automatic start-up with four different initializati
on modes 
• Preset parameters - only values deviating from the stan
dard need to be adjusted 
• Calibrated travel sensor without gears susceptible to wear 
• Sub initialization mode (substitution) allows the positioner 
to be started up in case of emergency whilst the plant is 
running without the valve moving through the whole travel 
range. 
• Permanent storage of all parameters in EEPROM (protec
ted against power failure) 
• Two-wire system with a small electrical load of 410
• Adjustable output pressure limitation
