OTIWTI™ Remote mount thermometer (AKM)

Capillary based, mechanical, remote indicating thermometer. Configurations for oil temperature measurement and winding temperature simulation. Features up to 6 adjustable switches for alarm, trip, and cooling system functions and can be equipped with various electronic outputs for SCADA and remote monitoring applications.

• AKM bellows measurement with resettable maximum pointer
• Up to 6 fully independent and user adjustable switches (contacts) for control and alarms.
• Switches can be specified by switch type, hysteresis range, and set point, without limitation of sequential set points.
• Internal winding temperature simulation without heated well
• 6 inch (150 mm) dial face with an angular dial span of 260° for maximum ease of measurement interpretation.
• Built in spring loaded pointer for switch field testing

The next generation thermometer from the global leader 

• Over 75 years of experience designing mechanical temperature measurement devices for transformers
• Over 250000 capillary type thermometers in service worldwide in all environmental conditions
• Improved connection ease with a greater number cable glands; 3 x M25 style and 2 x M20 style
• Improved switching flexibility with up to 6 fully configurable switches
• New and improved swing out case design allows for easy cable connection, switch configuration and testing without removal of the cover

Accomplish the most demanding control and alarm configurations 

• Up to 6 fully independent switches flexible enough for most control and alarm schemes
• Each switch can be specified by switch type, hysteresis range, and set point, without limitation of sequential set points
• Standard switch rated for up to 15 Amps AC and up to 10 Amp DC, switches also available for higher VDC (magnetic blow out, M.B.O.), and switches for milliamp loads
• Various analog outputs also available (mA, Pt 100, and Cu 10)
• Each switch can be specified with adjustable hysteresis (5 to 25°C)

Reduce failure costs with reliable AKM bellows operation 

• Non-pressured bellows system better resists leakage when compared to bourdon tube (pressurized) style capillary thermometers
• Integrated heating element in bellows for winding temperature indication eliminates extra cost and complexity of accessories to simulate the winding
• AKM bellows system provides a 260° dial deflection (angle the pointer travels from minimum to maximum) making it easier to interpret temperature reading from a distance

Minimize installation complexity with all-in-one design 

• Single enclosure design minimizes need for additional accessories such as matching units and heated wells commonly used by other mechanical temperature solutions
• New hinged cover enables easy access to switch settings and connections during installation while shielding device from elements. Features all captive screws and can be completely removed, if necessary
• Same installation footprint and mounting options as the previous generation AKM 345
• Improved wiring installation with addition of 2 cable glands (for a total of 5) and an increase in size to 3 x M25 and 2 x M20 versus the previous generation

Simplify operations by using one family of thermometer for all environmental conditions 

• Wide range of options allow for standard use of one thermometer series across a wide array of applications and operating conditions
• Extreme temperature survivability with polar executions for use down to -60°C
• Enclosures with IP55 or IP65 rating with numerous mounting configurations available
• The most flexible switching capabilities available for implementation of any control and alarm configuration
  
   

• Temperature ranges applicable for oil (liquid) or winding (winding temperature simulation does not require heated well)
• Up to 6 user adjustable switches with independent switch types
• Mounting style, tank connection style, probe length, capillary (length, material, protective housing), compatible well (pocket)
• SCADA outputs (0-1mA, 4-20mA, Pt 100, and Cu 10), analog and digital remote indicators

For temperature indication with integrated control and alarm functions. Designed for use where the point of measurement (the well or pocket) is not easily viewed by personnel requiring separate or remote indication.
