Бренд: Пентроник (Швеция), a Nordic manufacturer of high-precision temperature sensors. А 5810080 series is an assembled industrial Pt100 Resistance Temperature Detector (РТД). It is often mistakenly referred to as a thermocouple in the industry; this distinction is critical.
- Пояснение кода модели
5810080: Серия продуктов, assembled industrial platinum RTD with terminal head and protection thermowell
-001: Версия / construction suffix, representing single Pt100 element, Class A accuracy, base version with standard thermowell material, probe length and thread specification
Other variants within the series include 5810080-002 и 5810080-003, commonly dual Pt100 elements, alternative probe lengths or pressure ratings.
- Основные технические характеристики
| Элемент | Спецификация |
| Чувствительный элемент | Pt100 Platinum RTD (compliant with IEC60751) |
| Класс точности | Класс А |
| Температурный диапазон | -200℃ ~ +500℃ (depends on thermowell material) |
| Конфигурация проводки | Standard 4-wire (3-wire optional). The 4-wire design eliminates lead resistance error and is preferred for high-precision measurement |
| Thermowell Material | 316л нержавеющая сталь (стандартный); Hastelloy or Titanium optional for highly corrosive media |
| Probe Construction | Solid mineral-insulated / drilled protection tube, vibration-resistant structure (Pentronic thermally conductive filling for faster response) |
| Terminal Head | Aluminium waterproof head, IP65; built-in temperature transmitter optional (4-20mA output) |
| Монтаж | Threaded installation (Г1/2, M20×1.5 commonly used), compatible with protection thermowell |
| Время ответа | t0.5: приблизительно. 2~8s (in liquid media, subject to probe diameter) |
| СИЛ | SIL2 loop assessment available (dual-element version 5810080-002) |
- Основные функции
- Excellent stability: Class A platinum wire with annual drift as low as 0.05℃, suitable for long-term continuous process measurement
- Vibration-resistant construction: Internal metal filling reduces air gaps, withstands vibration for temperature measurement on compressor, pump and turbine casings
- Replaceable insert: Sensing element is a removable insert. Sensor core can be replaced without removing the thermowell, cutting downtime maintenance cost
- Corrosion-resistant options: Custom Hastelloy and Monel thermowells available for corrosive chemical service
- Дополнительные аксессуары: Built-in HART temperature transmitter providing direct 4–20mA signal to DCS/PLC
- Типичные сценарии применения
Пентроник 5810080-001 Датчик температуры
Thermal power, масло & газ, химический, paper and pharmaceutical industries; temperature measurement of pipelines, equipment casings and tank media; high-precision temperature acquisition for TSI and process control loops.
Frequently paired with Bently Nevada TSI systems for unit temperature monitoring.
- Установка & Руководство по вводу в эксплуатацию
- Установка: Protection thermowell is recommended for online replacement. Probe insertion depth ≥ 8~10 times thermowell inner diameter to ensure accurate temperature reading
- Электропроводка: 4-wire Pt100 with two excitation wires and two measurement wires. Must not be used with thermocouple extension wires
- Экранирование: Cable shield single-point grounded inside terminal head to avoid common-mode interference; route away from power cables
- Калибровка: Calibrate resistance values against IEC60751 using dry block calibrator or constant temperature oil bath
- Explosion-proof versions: С этого момента / Ex d available; certificates must be verified for hazardous area selection
- Common Troubleshooting Checklist
- Temperature fluctuation: Loose lead connections, multi-point grounding of shield, terminal loosening caused by field vibration
- Persistently high / low readings: Probe not fully immersed in media, fouled thermowell, excessive lead resistance (switch to 4-wire configuration)
- Open circuit alarm: Broken platinum wire or bending damage at root (frequently seen under vibrating conditions)
- Increased drift: Platinum element aging after prolonged over-temperature operation
