SAMSON 3730 Original High Performance Hart digital smart feedback 3730-2 3730-3 valve positioner
Product Details
Product Description
1. Description
Electropneumatic positioner with HART® communication
SAM DIGITAL READY
Die-cast aluminum or stainless steel housing
Attachment to linear actuators according to IEC 60534-6, VDI/VDE 3847, or SAMSON integral attachment
Attachment to rotary actuators according to VDI/VDE 3845
Attachment to double-acting actuators with Type 3710 Reversing Amplifier
Integrated EXPERTplus diagnostics for control valves
Any desired mounting position of the positioner (but not suspended)
Simple one-knob, menu-driven operation
Easy-to-read display in any mounting position, thanks to rotatable reading direction
Configurable with a computer over the SSP interface using the TROVIS-VIEW software
Variable automatic start-up thanks to four different initialization modes
Preset parameters, only values deviating from the standard need to be adjusted
Calibrated travel sensor without gears susceptible to wear
Sub (substitution) initialization mode allows the positioner to be started up in case of emergency, whilst the plant is running, without having to change the valve position.
All parameters are saved in non-volatile EEPROM
Two-wire system with a small electrical load of 410 Ω
Adjustable output pressure limitation
Adjustable tight-closing function
Automatic zero monitoring
Integrated temperature sensor and operating hours counter
Two standard programmable position alarms
Self-diagnostics
Messages as condensed state conforming to NAMUR Recommendation NE 107, issued over a fault alarm contact or optional analog position transmitter
DTM file available for integration into FDT frame applications according to specification 1.2
2. How to order

Samson 3710 Reversing amplifier with pressure gauge double acting
Official Website Reversing amplifier to operate a double-acting pneumatic actuator using a single-acting pneumatic or electropneumatic positioner or limit switch
E+H RIA15 process indicator Loop-powered Ex ia process indicator as field or control panel device fo
RIA15 process indicator The process indicator is available with 4 to 20 mA or with HART® protocol. In the HART® version up to 4 measured values of one sensor can be indicated in alternation. For this, the indicator can be set as a primary or secondary HART® master and actively inquire the values from the sensor. The small voltage drop of < 1V (< 1.9 V with HART®) is a huge advantage, especially in Ex-applications, where in most cases only a reduced voltage is available.
Flowserve Pneumatic Actuators - Linear - VL Series VL25 Valtek
VL Actuator Valtek VL series spring cylinder linear actuators are powerful, compact, high-performance pneumatic actuators that provide solid throttling or on-off operation for automatic control valves. The positioner supplies air to both sides of the piston, providing stiff, precise movement and high-frequency response and quick stroke speeds.
