Key parameters
Measuring range
−50 to 150 °C (−58 to 302 °F); −50 to 200 °C with extension neck
Output
1× PNP; 2× PNP; or PNP + active 4–20 mA
Supply
12 to 30 VDC
Process connection
Hygienic: conical metal-metal G½"; Clamp 1"–2" DIN 32676; Varivent F/N; DIN 11851; APV Inline
Wetted parts
Process connection AISI 316L
Ambient temperature
−40 to 85 °C
Fits hygienic temperature switching where you need a Thermophant T TTR35 Pt100 switch with PNP or PNP+4–20 mA outputs and 3-A documented wetted design.
Key advantages
- Range — −50 to 150 °C (−58 to 302 °F); to 200 °C with extension neck
- Sensor — Pt100 Class A (IEC 60751); FDA-compliant hygienic design
- Outputs — 1× PNP; 2× PNP; or PNP + active 4–20 mA
- Hygiene — 3-A mark; hygienic connections (Clamp, Varivent, DIN 11851, etc.)
- Response — t50 < 1.0 s; t90 < 2.0 s in flowing water (IEC 60751)
Typical applications
- Dairy, beverage, and hygienic process temperature switching.
- Compact sanitary points needing local display and PNP outputs.
- Loops that want switch plus active 4–20 mA from one device.
Selection guide
- Output — 1× PNP vs 2× PNP vs PNP + 4–20 mA
- Connection — Clamp / Varivent / DIN 11851 / conical metal-metal G½"
- Neck — Extension neck if process approaches 200 °C class
- Protection — IP65/IP66; IP69K optional with locking connector
Common mistakes
- Ordering without extension neck when process exceeds ~150 °C at the sensor.
- Assuming relay dry contacts — outputs are PNP (and optional mA).
- Skipping hygienic certificate needs on the RFQ.
When to RFQ / what to tell us
- Span, output configuration, hygienic connection.
- IP69K / neck options; supply 12–30 VDC.
- Quantity and ship-to.
