2 Safety instructions
- The device described is a subcomponent for integration into a system.
- The manufacturer is responsible for the safety of the system.
- The system manufacturer undertakes to perform a risk assessment and to create a documentation in accordance with legal and normative requirements to be provided to the operator and user of the system. This documentation
must contain all necessary information and safety instructions for the operator, the user and, if applicable, for any service personnel authorised by the manufacturer of the system.
- Read this document before setting up the product and keep it during the entire service life.
- The product must be suitable for the corresponding applications and environmental conditions without any restrictions.
- Only use the product for its intended purpose (→ Functions and features).
- Only use the product for permissible media (→ Technical data).
- If the operating instructions or the technical data are not adhered to, personal injury and/or damage to property may occur.
- The manufacturer assumes no liability or warranty for any consequences caused by tampering with the product or incorrect use by the operator.
- Installation, electrical connection, set-up, programming, configuration, operation and maintenance of the product must be carried out by personnel qualified and authorised for the respective activity.
- Protect units and cables against damage.
CAUTION
For high medium temperatures, parts of the unit may heat up.
Risk of burns
▶ Do not touch the unit
▶ Protect the housing against contact with flammable substances and unintentional contact.
3 Functions and features
The pressure sensor detects the system pressure and converts it into an analogue output signal.
3.1 Applications
• Type of pressure: relative pressure
| Order number | Final value of the measuring range (nominal pressure) | Static pressure resistance (max. permissible pressure) | Bursting pressure |
| psi psi psi | |||
| PU1760 0 | ..8000 20000 36250 | ||
| PU1700 0 | ..5000 14500 24650 | ||
| PU1701 0 | ..3600 9000 17400 | ||
| PU1732 0 | ..3000 7250 14500 | ||

| PU1743 0 | ..500 1450 11600 |
Avoid overload pressure exceeding the specified maximum permissible pressure by taking appropriate measures.
The indicated bursting pressure must not be exceeded.
Even if the bursting pressure is exceeded only for a short time, the unit may be destroyed. ATTENTION: Risk of injury!
For units with a final value of the measuring range of 8000 psi the limits of the pressure cycles across the lifetime apply ( → 7).
If the cable length exceeds 30 m or if used outside buildings, there is a risk of overvoltage pulses from external sources. We recommend to use the unit in protected operating environments and to limit overvoltage pulses to max. 500 V.
Pressure Equipment Directive (PED):
- Units with a final value of the measuring range of 500...5000 psi comply with the Pressure Equipment Directive and are designed and manufactured for group 2 fluids in accordance with the sound engineering practice. Use of group 1 fluids on request!
Pressure Equipment Directive (PED):
The units with a final value of the measuring range of 8000 psi comply with the Pressure Equipment Directive. They are designed for group 2 fluids and manufactured and tested according to Module A.
Use of group 1 fluids on request!
The units are vacuum resistant.
3.2 Use in hydraulic systems of mobile machines
Restrictor in the process connection:
In hydraulic systems of mobile machines, highly dynamic effects such as pressure peaks, cavitation etc. may arise depending on the operating conditions. To reduce these effects on the measuring element of the sensor, a diaphragm attachment is integrated into the process connection.
The specific thread pitch of the diaphragm attachment has the effect of a hole of 0.3 mm.
Please note:
High viscosity may reduce the response time by some milliseconds. Heavy soiling may affect the functionality.

Voltage output 0.5 ... 4.5 V (PU17xx)
line
| MEWMAW P | U [V] | | -------- | ----- | | 0 | 0.5 | | 1 | 4.5 |P = system pressure
MAW = initial value of the measuring range MEW = final value of the measuring range
In the measuring range, the output signal is between 0.5 and 4.5 V.
5 Installation
Before installing and removing the unit: Make sure that no pressure is applied to the system.
▶ Insert the unit in a 9/16-18 UNF process connection.
▶ Tighten firmly. Recommended tightening torque:
| Final value of the measuring range in psi Tightening torque in Nm | |
| 500...5000 25...35 | |
| 8000 30...50 | |
| Depends on lubrication, seal and pressure rating! | |
6 Electrical connection
The unit must be connected by a qualified electrician. Voltage supply to EN 50178, SELV, PELV.
▶ Disconnect power.
▶ Connect the unit as follows:
PU17xx (0.5...4.5 V analogue)
| Deutsch DT04 3P | |
 |  |
| OUT: Analogue output 0.5...4.5 V | |
