Frequently asked questions
Common questions about DIGI-STEM from 3G Electric.
What temperature ranges do DIGI-STEM thermocouple probes cover?
DIGI-STEM Type K thermocouple probes are rated for a temperature range of -109°F to 900°F (-78°C to 482°C). This covers most industrial process heating and exhaust monitoring applications. The probes maintain accuracy of ±1.1°C at 277°C or ±2°F at 530°F, depending on the specific model. For lower-temperature applications, DIGI-STEM RTD probes cover -76°F to 399.2°F (-60°C to 204°C) with ±0.15°C accuracy.
What is the accuracy specification for DIGI-STEM RTD probes?
DIGI-STEM RTD probes, such as model DST507A21303B, offer an accuracy of ±0.15°C. This is typical for Class A platinum RTDs and supports precise temperature measurement in processes requiring tight control, such as chemical reactors or pharmaceutical equipment. The probes use a 316 stainless steel sheath for corrosion resistance and are available with a 1-1/4 x 18 NEF2 process mounting thread.
Are DIGI-STEM thermocouple probes available with different lead wire configurations?
Yes, DIGI-STEM thermocouple probes are offered in multiple SKUs with varying lead wire lengths and terminations. For example, SKU 19RU66 (MPN DSTPA1223204) and SKU 19RU65 (MPN DSTPA420632112) are both Type K probes with lead wires but differ in probe length and lead wire specifications. The part number suffix indicates the configuration, allowing selection based on installation distance and connection requirements.
What sheath material is used in DIGI-STEM RTD probes?
DIGI-STEM RTD probes, such as the DST507A21303B, use 316 stainless steel as the probe sheath material. This provides resistance to corrosion in moist or chemically aggressive environments, making the probes suitable for use in chemical processing, water treatment, and food production facilities. The 316 stainless steel also offers good mechanical strength for threaded installations.
Can DIGI-STEM thermocouples be used in high-vibration environments?
DIGI-STEM thermocouple probes are standard Type K designs with lead wires, intended for general industrial use. While they are not specifically rated for high-vibration applications, the probes can be installed in environments with moderate vibration if properly supported. For high-vibration settings, consider using a thermowell or a probe with a heavier sheath. Consult the datasheet for specific mechanical limits.
What is the process mounting thread size on DIGI-STEM RTD probes?
The DIGI-STEM RTD probe model DST507A21303B features a process mounting thread size of 1-1/4 x 18 NEF2. This is a National Extra Fine thread standard, commonly used in industrial temperature sensor installations. The thread allows direct mounting into process piping or tanks with compatible fittings, ensuring a secure seal and accurate temperature measurement.
