OM-CP-HITEMP140-M12-Logger

Supported Applications

The Omega OM-CP-HITEMP140-M12 is a rugged, high-temperature data logger designed for environments requiring precise temperature monitoring up to extreme limits. The series supports applications including autoclave verification, food preparation and processing, environmental studies, well monitoring, washer disinfectors, and pasteurization.

Engineers select this device where probe interchangeability is required; the M12 connector allows quick connection of various RTD probes sold separately to satisfy diverse measurement needs with a single logger body. The unit features non-volatile solid-state memory that retains data even if the battery becomes discharged, ensuring record integrity in critical processes.

Operating Conditions & Performance

The OM-CP-HITEMP140-M12 operates within an ambient temperature range of -40 to 140°C (-40 to 284°F) and a humidity environment of 0 to 100% RH non-condensing. The device is rated for pressures from 0 to 60 psia.

Performance specifications are probe dependent, with the following documented capabilities:

• Measurement Range: -200 to 850°C (-328 to 1562°F) or 18 to 400 Ω.
• Resolution: 0.01°C (0.018°F).
• Calibrated Accuracy: ±0.05°C (±0.09°F); accuracy is based on standard calibrations for the -200 to 265°C (-328 to 509°F) range.

The logger records up to 43,690 time-stamped readings with a reading rate configurable from 4 readings per second down to 1 reading every 24 hours. In trigger settings mode (high and low limits), the memory capacity is reduced to 18,724 readings.

Power & Memory

The unit is powered by a user-replaceable 3.6V high-temperature lithium battery included with the device. Battery life is typical for 2 years at a 1-minute reading rate and 25°C (77°F). The internal clock maintains time accuracy of ±1 minute/month at 25°C.

Configuration Options

The series offers configurable options to extend functionality, connectivity, and compliance. Key capabilities include:

• Sensor Interface: M12 female, 4-pin connector compatible with Pt100 RTD probes (sold separately) requiring specific wiring configurations.
• Housing & Materials: Constructed from food-grade 316 Stainless Steel. The logger body is water-tight and rated IP40 alone; it inherits the IP rating of an attached probe, supporting up to IP68/IP69K when connected.
• Data Management: Supports software programmable immediate start or delay start up to 18 months in advance. Stop modes include manual or timed (specific date and time). Optional password protection restricts access to configuration options while allowing data readout without the password.
• Calibration & Compliance: Digital calibration is performed through software, with the calibration date automatically recorded within the device. An optional NIST calibration certificate is available via model OM-CP-HITEMP140-M12-CERT. The series supports FDA 21 CFR part 11 compliance using the OM-CP-SVP-SYSTEM validation package.

Accessories & Interfaces

Data retrieval and real-time monitoring require a computer interface via docking stations:

• OM-CP-IFC400: Docking station for a single data logger with USB cable, software, and manual.
• OM-CP-IFC406: Multiplexer interface accepting up to 6 data loggers.

The series also supports mounting options (OM-CP-MULTIMOUNT-Z), replacement batteries (OM-CP-BAT110), and aluminum briefcases for transport (OM-CP-ALUCASE-14, OM-CP-ALUCASE-18).

Key Product Differences

The primary distinction within the series is the inclusion of certification documentation. The standard model OM-CP-HITEMP140-M12 provides the high-temperature data logger with an M12 connector. The variant OM-CP-HITEMP140-M12-CERT includes a NIST calibration certificate.

The device body dimensions are 54.5 H x 24.6 mm dia (2.15 x 0.97") with a weight of 85 g (3.0 oz). The logger is approved for CE and RoHS compliance.
