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
Fisher 99H MR99H Pressure Reducing Regulator Valve
Specifications and ratings for various Type 99 constructions are listed in the Specifications section below. Some specifications for a given regulator as it originally comes from the factory are stamped on the nameplates located on the pilot and actuator spring cases. An additional nameplate may be installed on the pilot to indicate a regulator with O-ring stem seal. These regulators and their installations should be checked for compliance with applicable codes.
