Samson Type 3725 – Compact Electropneumatic Positioner for Pneumatic Valves

Product Overview

The Samson Type 3725 is a single-acting electropneumatic positioner for attachment to pneumatic globe and rotary valves. It is self-calibrating and automatically adapts to the valve and actuator. The device is simple, reliable, and commonly used in process plants where a compact, low-cost positioner is needed for basic control loops. It has a plastic housing (polyphthalamide) and an intuitive LCD with capacitive keys for easy operation.

Features

  • Self-calibrating with automatic adaptation to valve/actuator
  • Intuitive navigation menu with three capacitive keys
  • LCD display readable in any mounting position (rotatable reading direction)
  • Preset parameters – only non-standard values need adjustment
  • All parameters saved in non-volatile EEPROM
  • Tight-closing function can be activated
  • Non-contact position sensing
  • Unaffected by environmental effects and steam hammering

Technical Specifications

  • Reference variable w: 4 to 20 mA (two-wire, reverse polarity protection)
  • Split-range operation: 4 to 11.9 mA and 12.1 to 20 mA
  • Minimum current: 3.8 mA
  • Static destruction limit: ±33 V
  • Supply air: 1.4 to 7 bar (20 to 105 psi)
  • Air quality: ISO 8573-1 Class 4 (particles), Class 3 (oil), dew point 10 K below ambient
  • Signal pressure: 0 bar up to supply pressure, limitable to approx. 2.3 bar by software
  • Hysteresis: ≤0.3 %
  • Sensitivity: ≤0.1 %
  • Air consumption: ≤100 l n /h (with 6 bar supply and 0.6 bar signal)
  • Air output capacity: 8.5 m n ³/h (pressurized, Δp=6 bar); 14.0 m n ³/h (vented, Δp=6 bar)
  • Ambient temperature: –25 to +80 °C (limits apply for explosion-protected versions)
  • Degree of protection: IP66
  • Housing material: Polyphthalamide (PPA)
  • Weight: Approx. 1.0 kg

Applications

  • Attachment to pneumatic globe valves
  • Attachment to rotary actuators
  • Direct attachment to Samson Type 3277 actuator
  • NAMUR attachment (IEC 60534-6)
  • General process control where simple electropneumatic positioning is required

FAQ

Q: Does it auto-calibrate?

A: Yes – variable automatic start-up and self-calibrating.

Q: What attachments are possible?

A: Direct to Samson Type 3277, NAMUR, rotary actuators, and Type 3372.
