SR301

Sellos Remotos

The SR301 series is a complete line of Remote Seals, which allow the pressure transmitter to do measurements in situations where a direct contact of the transmitter’s diaphragm with process fluid is not allowed.

 

Basic Features

  • Remote seal transmitters are used when it is necessary to isolate the transmitter from the process.
  • The seal system comprises a process connection with a flexible diaphragm seal between the process fluid and a liquid filled capillary tube, connected to the transmitter.
  • The diaphragm isolates the process fluid while the filled capillary tube transmits the process pressure to the transmitter sensor.

 

Available Models

"T" Type Flanged Remote Seal - SR301T

The SR301T is a flanged seal with welded diaphragm. It can be supplied with an optional flush connection and housing.The flush connection removes deposits on the diaphragm without disconnecting the seal. If installed correctly, the seal flange is a non-wetted part and does not get wet in contact with the
process fluid during normal operation. However, the diaphragm and housing are wetted.
Bolts and nuts are not supplied with the seal.

 

Flanged Remote Seal with Extension - SR301E

The SR301E is a flanged seal with welded diaphragm. The diaphragm is extended from the seal flange and welded to the extension. Different from Model SR301T, it is not supplied with a housing, because the diaphragm coincides with the internal wall of the tank.
Bolts and nuts are not supplied with the seal.

 

Threaded Remote Seal - SR301R

The SR301R is a threaded connection seal. The diaphragm is welded to the flange. This model is always supplied with housing, because the process thread is located in this part. The flush connection (optional) in the housing enables the removal of deposits on the diaphragm without disconnecting the seal. The parts are bolted together and sealed with a gasket.
This model is supplied with bolts and nuts in Stainless Steel 316.

 

Sanitary Remote Seal - SR301S

The SR301S is a seal for food and other applications where the sanitary connections are necessary. The diaphragm is welded to the connection face, which can be Threaded type or Tri-Clamp, allowing an easy and fast connection/disconnection of the transmitter.

 

Pancake Remote Seal - SR301P

The SR301P is a seal with welded diaphragm, whose assembly requires blind flanges. This model is supplied with housing and flush connection (optional). The flush connection removes deposits on the diaphragm without disconnecting the seal. The seal diaphragm and the housing are wetted (in contact with the process fluid). However, the blind flange does not get wet.
Bolts, nuts and blind flange are not supplied with the seal.
The pressure limits are established by pressure class of the blind flange.
