The **PS86-104P-B-R2** is a high-precision, thin-film pressure transducer manufactured by **Nidec Components (formerly Copal Electronics)**. It is designed for industrial applications requiring high reliability and stability. Below is a breakdown of its technical specifications and electronic characteristics. --- ### 1. Part Number Breakdown Understanding the nomenclature helps identify the specific capabilities of this model: | Component | Code | Meaning | | :--- | :--- | :--- | | **Series** | PS86 | Thin-film pressure sensor series | | **Pressure Range** | 104 | 0 to 1.0 MPa (approx. 10 bar / 145 PSI) | | **Pressure Type** | P | Gauge Pressure (Positive) | | **Output Type** | B | 4–20 mA Current Loop | | **Interface/Seal** | R2 | R1/4 (PT 1/4) Tapered pipe thread | --- ### 2. Key Electronic Specifications The PS86-104P-B-R2 utilizes a **Thin-film (SUS316L)** diaphragm, making it highly resistant to corrosion and mechanical fatigue. | Parameter | Specification | | :--- | :--- | | **Rated Pressure Range** | 0 ~ 1.0 MPa | | **Maximum Pressure** | 2.0 MPa (2x rated range) | | **Excitation Voltage** | 12 ~ 24 V DC (±10%) | | **Output Signal** | 4 ~ 20 mA (Linear) | | **Accuracy** | ±0.5% F.S. (Full Scale) | | **Thermal Error** | ±0.05% F.S. / °C | | **Operating Temp** | -10°C to +70°C | --- ### 3. Wiring and Connection This device typically uses a 2-wire current loop configuration. In a 4-20mA system, the power and signal share the same lines. ```text Pin/Wire Color | Function | Description ---------------|---------------|---------------------------- Red | Power (+) | Connect to 12-24V DC Blue/Black | Output (Iout) | 4-20mA Signal / Return Path ``` --- ### 4. Application and Usage Because the sensing element is made of **Stainless Steel (SUS316L)**, this part is suitable for: * **Hydraulic Systems:** High-pressure oil monitoring. * **Water Treatment:** Measuring pressure in pipes without contamination. * **Industrial Gases:** Compatible with non-corrosive gases. * **PLC Integration:** The 4-20mA signal is ideal for long-distance transmission to a Programmable Logic Controller (PLC) as it is resistant to electrical noise. ---
