Temperature is a fundamental physical property that quantifies the hotness or coldness of a body, liquid, material, gas, etc. which could be expressed in different scales as shown below.

1. How is Temperature measured with the SRV and SRD?
The Rheonics SRV and SRD measure temperature by an internal PT1000 sensor which belongs to a class of sensors called RTDs.
The PT1000 is located in the probe tip and so measures the temperature of the fluid exactly where the viscosity and density of the fluid are measured. All off-the-shelf Rheonics sensors including SRV and SRD are capable of measuring fluid temperatures in real-time and displaying them on integrated display (option E1), Rheonics control panel (RCP), or transmitting them through various communication protocols to PLC and IPC.
The standard configuration for all Rheonics sensors is based on the standard DIN EN 60751 for tolerance, the B class is available as the standard tolerance class for the sensor probes. Depending on customer requirements class A and AA can be calibrated. The tolerance for different classes of RTD is as in the table below:
|Can be ordered
|Can be ordered
*abs(t)= absolute value of temperature in °C without regard to sign.

2. What Units are available in Rheonics SRV and SRD?
Diverse temperature units allow to have a standardized scale, where units are chosen according to customer preference and the industry or discipline where the measurement is applied.
°C: Represents the temperature in the Celsius scale.
K: Represents the temperature in the Kelvin scale.
°F: Represents the temperature in the Fahrenheit scale.
3. Why is it important to measure temperature?
Measuring Temperature in quality control ensures consistent material composition and adherence to standards. Also, it is a vital component in calculating the density with the SRD sensor. Accurate temperature control contributes to customer satisfaction by delivering reliable and high-quality products otherwise, some industries like pharmaceutical or food could have problems ensuring the safety for consumption.
