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 gases, liquids or solids 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.
