TEMPERATURE SENSORS

Now more than ever you need to safely and accurately measure cargo temperature in tanks and pipelines. Environmental concerns make manual gauging a challenging task, and until recently, a sometimes impossible feat. Our GUARD TEMP™ Barge Temperature Sensor is a reliable, cutting-edge solution that requires absolutely no cabling or wiring to precisely measure in-tank cargo temperature. Bergan’s Portable Readout Unit gives your crew the ability to easily monitor tank temperature up to three points at a time, safely and efficiently.

For more than 45 years, the professional team at Bergan Marine Systems has been designing and manufacturing high-quality marine instrumentation and equipment buitl to the highest standards required to guard life, property and the environment, and consistently exceeding expectations.

GUARD TEMP™ DTG

The GUARD TEMP™ Digital Temperature Gauge (DTG) is a fully digital tank temperature sensor designed for tank ships and tank barges that significantly saves on deck cabling, IS barriers and I/O cost. The simple 2-wire connection from the cargo tank to main control panel for all three measurement points is one advantage that makes this possible. Also adding value, GUARD TEMP™ DTG has three digital temperature sensors (daisy chained) per cargo tank. These digital temperature sensors connect to a sensor collection unit (SCU) with an optional LCD for local display.

The unit is certified Intrinsically Safe and is typically fitted into a shipyard provided thermowell or a FRAMO style deep well pump. Multiple mounting options are available with a one-inch minimum thermowell size. And, it can connect directly to CARGORADAR® or separately run to CCR with our 2-core cable.

Options include LCD readout at junction box.

GUARD TEMP™ STS-100/200

The GUARD TEMP™ Single Temperature Sensor (STS) series of tank temperature sensors are designed for tank ships and tank barges and can be fitted at one, two or three points per tank – with pump thermo well flange or high temp asphalt options.

Choose from a normal cargo temperature using a neoprene cable (STS-100 or the high- temp version with a Teflon jacketed cable (STS-200.) The Platinum-1000 (PT-1000) wire wound platinum Resistance Temperature

GUARD TEMP™ SPS-100

The GUARD TEMP™ Single Point Sensor (SPS-100) is a rugged stainless-steel insertion-type sensor for tank wall or typical cargo piping connections offering a number of options – including for small tanks.

The unit’s removable PT-1000 wire wound platinum Resistant Temperature Detection (RTD) type temperature sensors are fitted into an RTD to 4-20mA Intrinsically Safe certified converter. Probe length is customizable, while process connections can be either screw-on or flange connection. Cabling is required, and temperature readings are displayed on a console and/or a deck display.

Our Barge Temperature Sensor is a reliable, cutting- edge solution that gives your crew the ability to easily monitor tank temperature up to three points at a time, safely and efficiently.

Options include portable handheld readout PTRU.

GUARD TEMP™ BCTU

The GUARD TEMP™ Barge Cargo Temperature Unit (BCTU) is a rugged low-cost stainless-steel tank temperature sensor designed for tank barges providing fast, accurate measurements and – the biggest advantage – no more mess. To add to the convenience, the unit requires no permanent cabling and is easily installed in any tank opening of two inches or larger.

The GUARD TEMP™ BCTU is also highly adaptable. Choose from individual thermo wells of up to three different temperature measurement points. The PT1000 platinum wire wound temperature sensors are wired directly to a connector on top of the junction box. Instantaneous temperature measurements are taken with a GUARD TEMP™ Portable Temperature Display Unit (PTDU) – a separate unit connected to the BCTU. Options include fitted with or without sensor pipes into existing thermal well and fitted on GUARD LEVEL® Twin Alarm Sensor.
