Blue Sea Systems Submersible Temperature Sensor, 10,000 Ohm, IP68

Overview

The Blue Sea Systems 1820 is a submersible temperature sensor for Blue Sea devices that accept a temperature input. It is rated IP68, uses a 10,000 Ohm sensor at 25°C, and covers a working range from -40°F to 175°F (-40°C to 80°C).

This is the general-purpose probe in the Blue Sea range, so it suits battery compartments, lockers, and other onboard spaces where the sensor may be exposed to splash, condensation, or standing water. The 12 in (30.48 cm) lead and 16 AWG wires make it best suited to installations where the sensing point is close to the monitor or charger connection.

Installation is straightforward because the sensor mounts with double-sided tape and the two wires connect in either order. That keeps replacement work simple and avoids having to sort lead polarity during installation.

Key features

• IP68 submersible sensor body for wet locations around the boat
• 10,000 Ohm sensor at 25°C with a temperature range of -40°F to 175°F (-40°C to 80°C)
• Double-sided tape mounting for quick placement on a clean surface without drilling
• Non-polarized wire connection so either lead can go to either terminal
• 12 in (30.48 cm) lead with 16 AWG wires for short runs near the monitored point
• Works with Blue Sea Systems products that require this temperature sensor input

Compatibility and fit

Fit depends more on sensor type and mounting location than on boat size. The 1820 is the general-purpose submersible version, not the higher-temperature strap-on style used for exhaust or other hot pipe surfaces. On a boat, it makes sense anywhere the probe needs to stay in a damp area and read a moderate temperature range.

It is also the same sensor supplied with select Blue Sea temperature monitors and P12 battery chargers. Before ordering, the important check is whether your Blue Sea unit is set up for this sensor style and whether the 12 in lead length suits the mounting point on your boat.

Installation and setup

Mount the sensor to a clean surface with double-sided tape, place it close to the point you want to monitor, and route the short lead where it will stay protected from chafe and vibration. Because the sensor wires are non-polarized, either wire can connect to either sensor terminal on the receiving device.

Use on board

This sensor is a good match for owners replacing a failed Blue Sea probe or adding temperature feedback to a compatible Blue Sea electrical system. It fits boats where the sensor location may see washdowns, spray, or condensation, but does not call for a dedicated high-temperature exhaust sensor.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
