Description
DESCRIPTION
The SRI990 Analog Positioner with analog input 4…20 mA is designed to operate pneumatic valve actuators. It offers an easy
adjustment by means of switches and potentiometers. The modular structure of this positioner series enables conversion
from an analog to an Intelligent positioner by easily exchanging the electronics. The SRI990-T Electrical Position Transmitter
includes the optional Position Transmitter but no controller and no pneumatic components. The positon of the actuator is
given as 4…20 mA output signal.
Features
• Configuration by means of switches and potentiometers
• Load 300
• Low air consumption
• Stroke is 8…260 mm (0.3…10.2 in.)
• Angle range up to 95 °
• Supply air pressure up to 6 bar (90 psig), with spool valve up to 7 bar (105 psig)
• Single-acting or double-acting
• Mechanical travel indicator
• Optional 4…20 mA position transmitter
• Attachment to stroke actuators directly or according to IEC 534 part 6 (NAMUR)
• Attachment to rotary actuators according to VDI/VDE 3845
• Protection class IP 65 (IP 66 on request) and NEMA 4X
• Explosion protection: II 2 G EEx ib/ia IIB/IIC T4/T6 according to ATEX or “Intrinsic Safety” according to FM
• Additional equipment (compatible to SRD991):
◊ Integrated inductive limit switches, independent of device electronics
• Accessories (compatible to SRD991):
◊ Gauge attachment for supply air and outputs
◊ Booster relay
◊ SRI990 can be upgraded to an SRD991 by exchange of the electronic motherboard

Special Versions of SRI990
SRI990 Stainless Steel Housing
To be ordered with model code SRI990-Cxxxxxxx-xSZ.
SRI990 for Top Mounting onto Small Actuators
This version is designed for direct mounting on top of small actuators without a yoke—a solution for actuators up to
50mm stroke.
Instead of a rotary potentiometer, a Linearpoti is used that feeds back the actual position of the actuator.
Description
The Model Code of this basic device is SRI990-……ZZZ…-W
The adapter part is dependent on the manufacturer and type of actuator and can be ordered under the name EBZG-TMxx.
Please consult Badger Meter for the latest list of available adapter parts.

Description
SRI990 for Very Low Temperatures
With heating system for temperatures down to –60° C.
SRI990 for Actuator with Rotation up to 300°
This special version of the SRI990 is designed to be mounted by means of a standard attachment kit (like the EBZG-R) onto
rotary actuator with rotation up to 300°. This special version is made of a standard SRI990 with new gears.
To be ordered under special version ECEP EP0256.
