Strain gauge pressure sensor with a millivolt output direct from a four arm wheatstone bridge strain gauge circuit in pressure ranges from 10 up to 1000 bar gauge.
The TPS strain gauge pressure sensor utilises a robust stainless steel 17-4PH diaphragm with bonded foil strain gauges, and incorporates an innovative mechanical design which makes the sensor insensitive to tightening during installation.
The TPS strain gauge pressure sensor is ideally suited for applications that require high accuracy in dynamic pneumatic or hydraulic control & test systems, like material testing machines.

Product Description
Applications
Typically hydraulic methods are used to apply force or weight loading on a sample of material such as concrete or soil. When carrying out destructive testing high level pressure spikes are generated when samples start to weaken in reaction to the stresses being applied. It is important that the pressure sensor measuring the hydraulic pressure can tolerate this sudden change in pressure over many cycles without degradation of performance.
The TPS precision pressure sensor has a durable mechanical design and are used for high pressure material testing applications such as concrete or soil compression testing.
Sensing principle
Both the TPS strain gauge pressure sensor incorporates robust pressure sensor technology which includes a relatively thick 17-4ph stainless steel sensing diaphragm which is machined out of one piece of metal and high precision foil strain gauges which are precisely bonded to the reverse side to form a four arm wheatstone bridge circuit. The sensing element is mechanically designed in such a way to isolate it from mechanical stresses induced from tightening the pressure sensor during installation.
Pressure Ranges
The pressure ranges which run between 10 and 1000 bar can be over-pressured by up to two times their range without compromising specification tolerances.
Output Signal
The TPS precision pressure transducer has a mV signal output to provide a high dynamic signal response with passive circuitry.
Connections
A wide choice of pressure connections and electrical connections are available which make it possible to specify preferences for most installations.

Obsolete TFN replacement
We are looking for a replacement pressure transducer for our concrete cube compression strength test machine which measure a maximum force of 2000 kN. The old pressure sensor is marked TFN-V-7C, 700 bar, 3.0 mV/V.
The TFN is no longer manufactured, and we would suggest the TPS with the specification below as an alternative:
- SKU ID: s1-tps-96-28073
- Pressure Range: 0 to 700
- Units: bar
- Range Type: Positive Gauge (atm to +P)
- Output Signal: 3 mV/V
- Electrical Connection: 6 pin military style connector IP66
- Optional Mating Connector: 6 pin military style IP66 plus 2 metres of cable (C02W)
- Process Connection: G1/4 female
Hydraulic oil up to 700 bar
I need a hydraulic transducer for use on oil up to 700 bar with a 4 wire configuration which will operate from exciting 5V to 10V dc and output in mV.
The TPS is compatible with hydraulic oil and will work with any voltage betwen 5-10Vdc supply because it has a ratiometric input/output circuit, but bear in mind that the supply voltage will need to be stable to preduce a stable output.
- SKU ID: s1-tps-0001
- Part No: TPS-1-F-B07C-T 2130X000X00
- Pressure Range: 700
- Units: bar
- Range Type: Positive Gauge (atm to +P)
- Output Signal: 3 mV/V
- Electrical Connection: Integral shielded cable (1 metre long)
- Optional Mating Connectors: Not required
- Process Connection: G1/4 male (DIN3852-A)
