Low Temperature Passive Probes
LTP Series
DESCRIPTION
Honeywell’s Low Temperature Passive Probes, LTP Series,
are a modular range of temperature sensors designed for
potential use in transportation applications. The LTP Series
feature a durable, closed-tip design that maximizes reliability
in harsh applications. The sensor’s thermistor sensing element
effectively senses liquids and gases because of its enhanced
sensitivity, accuracy and reliability. Easy-to-install threaded
mounting provides reliable operation in harsh environments.
Numerous options—from mechanical and electrical interface—
simplify installation, allow customers to meet their specific
application needs, and facilitate backwards-compatibility with
most existing applications.
VALUE TO CUSTOMERS
The LTP Series are designed to meet the customer’s need for
sensors that are configurable, backwards-compatible, durable,
and that reduce total cost of ownership. Their flexible design
provides over 2,200 standard configurations with an enhanced
response time over a wide operating temperature range.
DIFFERENTIATION
• Seven probe lengths, four NTC thermistor sensor curves, 12
thread options ranging from M10 to M18, 3/4 UNF, and
G 1/4, and two hex options
• Zero NRE (non-recurring engineering) costs for configurations
• Reduces cost of ownership due to BOM (bill of materials),
engineering, testing, NRE and tooling
• Reduces design costs due to plug-and-play options,
backwards integration, flexible offering, customization and
non-standard offering
FEATURES
• Temperature range: -40 °C to 150 °C [-40 °F to 302 °F]
• Response time [T63.2% of 25 °C to 85 °C step]: stirred silicon
oil <15 s; stirred water <15 s; air flow 10 m/s <20 s
• Accuracy:
- -40 °C to 25 °C [-40 °F to 77 °F]: ±2.5 °C
- 25 °C to 100 °C [77 °F to 212 °F]: ±0.8 °C
- 100 °C to 125 °C [212 °F to 257 °F]: ±2.0 °C
- 125 °C to 150 °C [257 °F to 302 °F]: ±3.5 °C
• Electrical interface: Bosch Kompakt, Delphi Metri-Pack 150
Series, AMP Seal 16, AMP Minitimer, AMP Superseal 1.5
Series 2P, and Deutsch DT04-2P
• Probe length options: 20 mm to 50 mm (other lengths
available upon request)
• Mechanical fastening options: M10 to M18, 3/4 UNF, and
G 1/4 (other threads available on request)
• Retainer ring with hex: provides complete location for socket
wrench in axial and radial directions, enabling the operator
to first locate the sensor inside the socket to freely and more
easily install the sensor
• Insulation resistance between I/O pin and the sensor’s
housing: >10 MOhm at 250 Vdc, 25 °C [77 °F]
• Ingress protection: IP67
• Vibration: 30 g sine wave,10 Hz to 2000 Hz
• Mechanical shock: 50 g
• Service pressure: 10 bar
• Burst pressure: 40 bar
• Wire harness (with or without a connector) or other sensing
elements (PTC or RTD) available upon request
POTENTIAL TRANSPORTATION APPLICATIONS
• Ambient air temperature sensor
• Automatic transmission system
• Engine air inlet system
• Engine cooling system
• Engine lubrication system
• Fuel system
• Haldex coupling system
• Hydraulic pump systems
PORTFOLIO
The LTP Series joins the R300, 500, ES110, ES120, and 6655
Series that offer a variety of housing materials and styles,
terminations and R-T curves, depending on the customers’
application needs.
