1. PRODUCT INSPECTION
The pressure sensors are shipped only after stringent inspection at the factory. Upon delivery, check the
sensor according to the instructions given below.
(1) Visually check the sensor to ensure that it is free from damage.
(2) The model and suffix codes and the pressure range are indicated on the data plate attached to the
sensor. Cross-check this information with that in Table 2, 3 "Model and Suffix Codes" to ensure that the
sensor is as specified in the order.
Note: If the specifications of the ordered sensor are not standard, refer to the label tag attached to the sensor.
2. HANDLING PRECAUTIONS
2.1 Storage
(1) Store the sensor in a location that meets the following requirements.
• No exposure to rain or water
• No major mechanical vibration or shocks
• Humidity and temperature within the following ranges—preferably as close as possible to the
normal condition (25°C, 65% RH)
Temperature: −20 to 80°C; humidity: 5 to 95% RH (non-condensing)
• No corrosive gases
(2) Whenever possible, store the sensor in the same packaging that it was shipped in by the manufacturer.
(3) If the sensor has been put into use and the pressure-sensing chamber contains fluids, clean the
chamber thoroughly before storing the sensor.
Even when cleaning the sensor, exercise care to avoid damaging the seal diaphragms.
2.2 Installation Location
CAUTION
Never use the sensor in an environment containing any explosive gas. It is not designed to be explosion-
proof.
Although the pressure sensors are designed for use in severe environment, the following precautions
should be observed to ensure that the sensors are used safely and that they achieve the required accuracy
for a prolonged period.
(1) If it is likely that the sensor will be exposed to direct sunlight and/or other radiated heat, prepare some
kind of heat insulation for the sensor.
(2) Avoid installing the sensor in an environment containing any corrosive gas.
(3) Although the sensor is designed to be watertight, whenever possible, avoid installing it in a location
exposed to splashes of rain. Especially, prevent water from staying in the wiring inlet.
(4) Although the sensor is durable for vibration, install it in a location where mechanical vibration and/or
shocks are minimal.
2.3 Precautions to Avoid Damaging the Sensor
(1) When measuring pressure or cleaning the sensor, exercise care to avoid damaging the seal
diaphragms.
(2) The seal diaphragm may be damaged if the measured fluid within the pressure-sensing chamber
freezes. If it is likely to occur, prepare some kind of heat insulation etc. to avoid measured fluid from
freezing.
(3) The FP112/FP113 pressure sensors can withstand a pressure up to 200% of each measuring range.
(Normal clamp can withtand up to 1 MPa. When a pressure more than 1 MPa is applied at more than
500 kPa range, use a clamp that can withstand 2 MPa or more.) But take care not to apply a pressure
more than the maximum allowable pressure because piping condition and characteristics of pressure
source may cause an instantaneous burst of pressure.
2.4 Insulation Resistance and Withstanding Voltage Test Procedures
CAUTION
Carry out these tests only when absolutely necessary. Mistake in testing may result in electric shock to
the operator or damaging the sensor.
(1) Short-circuit the terminals except the ground terminal. For each test, apply the following voltages
across the short-circuited terminals and the ground terminal.
• Insulation Resistance Test: 500 V DC, for 2 minutes max.
Make sure the insulation resistance is 20 MΩ or more.
• Withstanding Voltage Test: 500 V AC, for 1 minute max.
Make sure the leak current is 1 mA or less.
(2) After the tests, connect a 100 kΩ resistor across the short-circuited terminals and the ground terminal
in order to discharge any internal charge.
2.5 Receiver Input Impedance
Use a receiver with input impedance of 10 kΩ or more for receiving the output signal (1 to 5 V DC) of the
FP112/FP113.

3. PRODUCT OVERVIEW
The FP112/FP113/FP212/FP213/FP211/FP211A pressure sensors can be used to measure gauge or
absolute pressure and output an electrical signal corresponding to the measured pressure. The sensors can
measure gas and liquid pressures directly with high accuracy and performance (e.g. temperature effects),
along with long-term stability.

- Power supply voltage: 24 V DC±1%
- Mounting position: Horizontal (position in Figure 8)
*2: The maximum allowable pressure for B or C range is 2 MPa. But normal clamp can withstand up to 1 MPa. When a
pressure more than 1 MPa is applied, use a clamp that can withstand 2 MPa or more.
