Rheonics STCM

Type-SR Temperature Control Modules (TCM)

Rheonics STCM is a line of devices that allow the viscosity and density measurement of static fluid at different configurable temperature points using Type-SR sensors:

Temperature Control

Control the temperature of the measured fluid with an internal heating and cooling module.

Temperature Stability

Keep stable the temperature of a heating/cooling fluid coming from an external source, to control the temperature of the measured fluid.

When is the STCM line useful?

Rheonics STCM devices are useful for laboratory and in-field mobile setups for the Rheonics Type-SR sensors. This allows static viscosity and density measurements or calibration procedures at specific temperature setpoints.

STCM is compact in size, similar to a standard coffee machine. The small footprint across all STCM variants added to the ability to achieve 10x better temperature stability and uniformity, are the main advantages of STCM line compared to commercial thermal chambers.

Application and Use Cases

STCM devices are designed to be used with Rheonics SRV Viscometer and SRD Density and Viscosity meter in all probe variants. The use of the STCM devices allow and are compatible with the following cases:

Static fluid viscosity and density measurements
Controlled temperature profiles
Laboratory setups
In-field mobile setups
Calibration verification of inline SRV and SRD sensors
Small fluid volume use

STCM Line Variants

STCM-PL	STCM-IFP	STCM-BTJ	CALIBRATOR
STCM with Solid State Heating/Cooling Temperature Control	STCM with Inline Fluid Profiler	STCM with External Bath	Rheonics in field Calibrator

Take a sample from the process and measure viscosity and/or density of the fluid. Control the fluid’s temperature with the in-built heating and cooling module.	Connect the device to the line, as in a bypass, and measure static viscosity of the fluid. Control the fluid’s temperature with the in-built heating and cooling module.	Take a sample from the process and measure viscosity and/or density of the fluid. Connect the BTJ to an external thermal fluid flow with the required temperature. The BTJ will transfer and maintatin the temperature to the measured fluid.	Use Rheonics Calibrator along with the Rheonics Calibrator Software to do calibration reports of the SRV and SRD sensors. A sample of the calibration fluid is required.
Compatible with all Type-SR probe variants thanks to interchangeable sample fluid cylinders.	Compatible with SRV and SRD G1/2” probe (SRx-X1-12G).	Compatible with all Type-SR probe variants thanks to interchangeable sample fluid cylinders.	Compatible with all Type-SR probe variants thanks to interchangeable sample fluid cylinders.
