Honeywell LTP Series Temperature Sensors

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.

• 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 < 15s; stirred water < 15s; air flow 10 m/s < 20s
• 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: Deutsch 2 position (AMP Minitimer,
Bosch Kompakt, Delphi Metri-Pack, AMP Seal 16, and AMP
Superseal connector style variants available upon request)
• Probe length options: 20 mm to 50 mm
• 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 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
