Honeywell KTF00-65-2M CableType Bulb Temperature Sensors

Product Information

The KTFxx cable-type bulb temperature sensors are versatile sensors that can be used as strap-on sensors or immersion sensors. They are suitable for hot and cold water installations in systems that use Pt1000, NTC 10k, or NTC 20k temperature sensing elements. The sensors feature stainless steel probes and have an IP65 rating for high accuracy.
The KTFxx sensors are available in various models:

• KTF00-65-2M: Pt1000 sensor with a 2-meter cable
• KTF10-65-2M: NTC 10k sensor with a 2-meter cable
• KTF20-65-2M: NTC 20k sensor with a 2-meter cable
• KTF10-65-2M-B: NTC 10k sensor with a 2-meter cable, pack of 50
• KTF20-65-2M-B: NTC 20k sensor with a 2-meter cable, pack of 50
• KTF20-65-5M-B: NTC 20k sensor with a 5-meter cable, pack of 50
• KTF00-65-2M-300: Pt1000 sensor with a 2-meter cable and a temperature range of up to 300°C

The sensors have a high accuracy and are made of stainless steel (1.4571) for durability. The cable sheath material is PVC, except for the KTF00-65-2M-300 model, which has PTFE. The electrical connection is a 2-m or 5-m cable with 2×0.22 mm2 wires. The sensors have an IP65 rating for safety.

GENERAL

The KTFxx cable-type bulb temperature sensors can be used as strap-on sensors or immersion sensors. The sensors can be employed for hot and cold water installations in systems using Pt1000, NTC 10k, or NTC 20k temperature sensing elements.
