OM-CP-HITEMP140-FR-LOGGER

Supported Applications

The OM-CP-HITEMP140-FR is a high temperature data logger with a 50 mm (2") fast response probe, built to record temperature during rapidly changing thermal processes with an ultra-fast response time. Its applications include oven profiling, steam sterilization, autoclave verification and mapping, and seafood processing.

Because the probe reaches thermal equilibrium quickly and the stainless steel body is submersible to IP68, the logger is well suited to wet, high-temperature cycles where a slower sensor would lag the true process temperature.

Operating Conditions & Performance

The logger uses a 100 Ω platinum RTD and measures a probe range of -200 to 260°C (-328 to 500°F), with a resolution of 0.01°C (0.02°F) and a calibrated accuracy of ±0.1°C (±0.18°F) from 20 to 140°C (68 to 284°F).

• Response time in air: reaches 60% of the step change in 39 sec and 90% of the step change in 2 min 71 sec.
• Response time in water: reaches 60% of the step change in 10 sec and 90% of the step change in 12 sec.
• Reading rate: up to 4 Hz (4 readings per second) up to 1 reading every 24 hours.
• Memory: 32,767 readings, or 10,922 readings in trigger settings mode.
• Ambient operating temperature: -40 to 140°C (-40 to 284°F).
• Enclosure rating: IP68.
• Humidity: 0 to 100% RH.
• Power: 3.6V high-temperature lithium battery (included; user replaceable).

The probe diameter is 50 mm (2") with a 44.5 mm (1.75") stem, and the logger body measures 48 H x 24.6 mm D (1.89 x 0.970"), weighing 65 g (2.3 oz). Wetted materials are 316 Stainless Steel and PEEK. The device carries CE and RoHS, with optional NIST calibration and optional 5 YEAR WARRANTY. It requires the OM-CP-IFC400 USB docking station or OM-CP-IFC406 multiplexer interface for operation.

Configuration Options

The series centers on the OM-CP-HITEMP140-FR data logger, with configuration options that add a thermal shield and/or a calibration certificate:

Base logger (without thermal shield)

The OM-CP-HITEMP140-FR alone delivers the fastest response — in water it reaches 60% of the step change in 10 sec and 90% in 12 sec — and is the configuration used where the probe can be immersed directly in the process.

With thermal shield

Adding a PTFE thermal shield lets the logger survive time-limited exposure to a -200 to 250°C (-328 to 482°F) operating environment. The vented OM-CP-HITEMP140-FR-TSK uses a 109 x 51 mm dia (4.3 x 2.0") enclosure weighing 270 g (9.5 oz) not including the data logger, while the flush OM-CP-HITEMP140-FR-TSK-FL uses a smaller 70 x 51 mm dia (2.75 x 2.0") enclosure weighing 190 g (6.7 oz) not including the data logger.

Certification

Any of these configurations can be ordered with a NIST calibration certificate using the corresponding -CERT part number.

Key Product Differences

The model lineup consists of the logger, its thermal-shield configurations, and required interfaces:

• OM-CP-HITEMP140-FR — high temperature data logger with 50 mm (2") fast response probe.
• OM-CP-HITEMP140-FR-CERT — same logger with a NIST calibration certificate.
• OM-CP-HITEMP140-FR-TSK — OM-CP-HITEMP140-FR data logger and vented thermal shield.
• OM-CP-HITEMP140-FR-TSK-FL — OM-CP-HITEMP140-FR data logger and flush top thermal shield.
• OM-CP-IFC400 — docking station (for single data logger) with USB cable, software and manual.
• OM-CP-IFC406 — multiplexer data logger interface (accepts up to 6 data loggers) with USB cable, software and manual.
• OM-CP-BAT110 — replacement 3.6V high temperature lithium battery.
