iTHERM CompactLine TM311 sanitary thermometer provides accurate and fast process temperature measurements in hygienic and aseptic applications. Its temperature sensor offers a 4-wire connection or feeds into a smart temperature transmitter with 4 to 20 mA, IO-Link (auto-detect) or switch output. Featuring TipSens technology, the RTD (Pt100; Class A) delivers response times as low as 1.5 s (t90) for optimum process control. This versatile device is a great choice to drive plant standardization.

• Developed for universal use in sterile applications

• High standardization potential for skid builders, machine and plant manufacturers

• Measuring range: -50 to 200 °C (-58 to 392 °F)

• Pressure range: Up to 50 bar (725 psi)

• Protection class: IP69

• Output: Pt100 (4-wire connection); IO-Link, 4 to 20 mA, 1x PNP switch

• International approvals: 3-A, EHEDG, ASME BPE, FDA, EC 1935/2004, EN 2023/2006, TSE/ADI, GB4806-2016, GB9685-2016; Marine approval acc. to DNV GL

• Fast installation and easy commissioning:
  - Compact dimensions for installation in tight spaces
  - Standard M12 connector with IP69 for easy electrical connection
  - Recommended process immersion lengths for optimum measurement
  - Preset temperature range
