Pyxis ST-500SS-T Inline Drop-In Stainless Steel PTSA Sensor (requires ST-009 Tee)

Model:
ST-500SS-T
Brand:
Pyxis

The Pyxis ST-500SS-T is a drop-in inline PTSA fluorometer with a stainless steel body for high-pressure service, used to track inhibitor dose in fluorescence-traced water treatment programmes across a 0-500ppb range. It must be installed with the ST-009 stainless tee, sold separately, and outputs via 4-20mA analog and RS-485 Modbus through a 7-pin connector.

Extended measurement range — covers 0-500ppb, wider than standard PTSA sensor variants
High-pressure durability — stainless steel drop-in body rated for high-pressure service
Extended measurement range — covers 0-500ppb, wider than standard PTSA sensor variants

Description

The Pyxis ST-500SS-T is a drop-in inline PTSA fluorometer with a stainless steel body for high-pressure service, used to track inhibitor dose in fluorescence-traced water treatment programmes across an extended 0-500ppb range.

It uses a drop-in sensor design and must be installed with the ST-009 stainless tee, which is sold separately, so it is best specified alongside that tee for new installations rather than as a standalone replacement.

Output is via 4-20mA analog and RS-485 Modbus through a 7-pin connector, integrating with standard plant control systems for continuous dose monitoring at higher inhibitor concentrations.

Why Use This

Wider Measurement Range

The 0-500ppb range covers higher inhibitor dosing programmes than standard 0-200ppb PTSA sensors.

Built for High-Pressure Service

A stainless steel drop-in body is rated for high-pressure inline installations when paired with the ST-009 stainless tee.

Standard Control Integration

4-20mA analog and RS-485 Modbus outputs through a 7-pin connector allow straightforward wiring into plant control systems.

Applications

  • Higher-dose inhibitor programmes — 0-500ppb range suited to elevated PTSA tracer concentrations
  • High-pressure inline installations paired with the ST-009 stainless tee
  • PLC/SCADA-integrated inhibitor dose monitoring

FAQ

Does this sensor come with the tee needed to install it?

No, the ST-500SS-T is a drop-in sensor design that must be used with the ST-009 stainless tee, which is sold separately.

How is this different from the ST-500SS?

The ST-500SS-T covers an extended 0-500ppb range, wider than the standard 0-200ppb range, and uses a drop-in design requiring the separate ST-009 tee rather than being installed as a self-contained assembly.

What body material does it use?

It has a stainless steel body built for high-pressure service.

How does it connect to plant control systems?

Output is via 4-20mA analog and RS-485 Modbus through a 7-pin connector.
