THERMO VSTH

THERMO VSTH

Product catalog summary
General Characteristics
The VSTH temperature probe is designed for industrial applications, offering a compact and rugged construction with a minimum protection degree of IP65. It supports PT100, PT1000, and NiCr-Ni sensors and is available in ATEX intrinsically safe versions upon request.

Technical Data
The probe supports various configurations:
  • PT100 and PT1000: 2, 3, or 4 wires, temperature range from -50 to +400°C with rigid pipe, and -50 to +600°C with flexible pipe.
  • NiCr-Ni: 2 wires, temperature range from -200 to +1000°C with rigid pipe, and -200 to +1150°C with flexible pipe.
Class B is standard, with Class A available on request. Standards include DIN EN 60751 and DIN EN 60584-2.

Process Connections and Materials
The probe dimensions and thread options include standard sizes of Ø6 mm and threads of 1/2", 3/8", and 1/4". Materials used are V4A (316-L 1.4404) for PT100/1000 and Inconel 600 for NiCr-Ni.

Electrical Output
The probe offers various electrical outputs:
  • 4-20 mA for PT100, PT1000, and NiCr-Ni with programmable ranges.
  • 0-10 V for PT100 with a range to be defined.
ATEX certification is available for certain models, and a heatsink spacer is required for temperatures over 85°C.

Nomenclature
The nomenclature includes type, sensing element, process connection, probe diameter, probe length, and electrical output. The probe length (L0) and heatsink spacer length (LH) are customizable, with standard lengths of 100 mm.
