Supported Applications
The Omega Linear Thermistor Sensors (Series OL-701 and OL-702) are precision temperature sensors designed for general-purpose measurement. These probes combine two thermistors with matching resistor sets to provide a linear response, distinguishing them from standard non-linear thermistors. Documented applications include measuring soil temperatures where the sensor can be buried, short-term water readings, sub-soil measurements, and cuvette temperature monitoring.
Operating Conditions & Performance
The series operates within a process temperature range of 0 to 100°C (32 to 212°F). Interchangeability is specified at ±0.15°C. The sensors utilize the 44018 thermistor model, featuring resistance values of 6000Ω and 30000Ω at 25°C.
Physical dimensions for the standard configuration include an overall length of 371.6 (14.63) mm and a diameter of 3.6 (9/64) mm. The probes are supplied with 3 m (10') of PVC insulated cable.
Configuration Options
The series offers configurable terminations and tip constructions to suit specific installation needs:
- Sensor Types: Available as vinyl-sleeved tips or soft, flexible vinyl-tipped versions (OL-701-V).
- Terminations: Standard options include stripped leads or a phone plug connector (specific to the OL-701-PP model).
- Cable Construction: All models feature 3 m (10') of PVC insulated and jacketed cable.
The series supports waterproof construction for rugged use in water and sub-soil environments, as well as water-resistant flexible versions. While the broader Series 700 includes stainless steel tubular probes, glass immersion probes, and surface temperature configurations (such as OL-731 through OL-729), these specific variants are distinct from the lead-wire thermistor probe models covered in this series bundle.
Key Product Differences
The primary distinctions within the OL-701 and OL-702 family relate to tip flexibility, ruggedness, and termination style:
- OL-701: A general-purpose probe with a vinyl-sleeved tip. It is described as the most rugged option for short-term water and sub-soil readings, featuring waterproof construction.
- OL-701-V: A water-resistant version of the OL-701 that features a soft, flexible vinyl-tipped design.
- OL-702: Characterized as small and flexible with both a vinyl sheath and tip. This model is intended for cuvette temperatures and general-purpose measurement.
