Simarine Temperature Sensor 1m

Simarine 1m Waterproof Temperature Sensor for Precision Monitoring

Achieve unparalleled accuracy in your environmental data with this robust NTC thermistor. Engineered specifically for integration with advanced monitoring platforms, this waterproof probe delivers critical thermal data to protect your electrical components, battery banks, and fluid tanks. Whether you are outfitting a marine vessel, a touring caravan, or a remote off-grid power system, reliable thermal monitoring is a crucial step in preventing equipment degradation and ensuring safe operational thresholds.

Advanced NTC 5K Thermistor Technology

At the core of this unit is a highly sensitive NTC (Negative Temperature Coefficient) thermistor with a 5K resistance rating and an impressive 1% accuracy tolerance. Combined with a 3950 B-value, this sensor provides exceptional precision across a wide thermal range. This tight tolerance means the resistance curve remains highly consistent, allowing compatible monitoring displays to report exact thermal conditions rather than rough estimates. When tracking the temperature of sensitive lithium battery banks or monitoring engine bay climates, this level of precision drastically reduces the risk of undetected thermal events.

Durable, Waterproof Brass Construction

Harsh environments demand resilient components. This unit features a cylindrical brass probe housing that not only protects the delicate internal thermistor but also offers excellent thermal conductivity. This ensures rapid response times to environmental changes, giving you real-time data when it matters most. The probe is fully waterproof, making it highly suitable for applications where moisture, condensation, or direct liquid contact might compromise standard sensors. From monitoring fresh water tank temperatures to keeping an eye on external weather conditions, the robust construction ensures long-term reliability.

Flexible and Straightforward Installation

Designed for seamless integration into your existing monitoring network, the sensor comes pre-wired with a 1-metre black insulated cable. This length provides ample flexibility for routing wires through tight bulkheads, battery compartments, or behind control panels. The cable terminates in pre-stripped wire leads, allowing for immediate connection into standard terminal blocks or directly into modules like those used in advanced battery and tank monitoring systems. This eliminates the need for proprietary connectors and streamlines the installation process for both DIY enthusiasts and professional installers.

The Importance of Precision Thermal Data

Operating high-capacity battery systems or managing fluid storage requires vigilance. Charging lithium batteries below freezing or allowing lead-acid banks to overheat can cause irreversible damage and pose significant safety risks. By integrating a dedicated, high-accuracy probe into your system, you empower your charge controllers and monitors to adjust parameters dynamically or trigger alarms before critical limits are breached. Upgrading from generic grade sensors to a precision-engineered thermistor provides peace of mind when operating off the grid.
