Double tightening detection provides highly reliable prevention of missed tightening (Pokayoke). The R-256FH receiver has been upgraded to the downward compatible R-CM. This upgrade offers New Telecommunication Mode to increase transceiving distance, and lets operators monitor transmitter battery voltage.

[The Double Tightening Detection System] The CSPFHW series uses a gyro sensor to detect angle data, to make double tightening judgments.

• At stage 1, angle detection starts when trigger torque is reached, and a light clicking sensation is felt (at position “a”). At stage 2, when the set torque is reached, a strong clicking sensation with a distinctive clicking sound is felt (at position “b”).

• If the rotated angle is less than the set double tightening judgment angle (a - b'), double tightening is determined, resulting in a “NG” (No Good) judgment.

Example of CSPFHW model in use

Application

  • Prevents human tightening errors (Pokayoke)
  • Double Tightening Prevention

Features

  • Comes with double tightening detection to permit highly reliable “pokayoke” error proofing.
  • When the CSPFHW is used to retighten bolts and nuts that have already been tightened once, the action will be judged as double tightening, causing NG (“No Good”) to be displayed and the LED light to show red.
  • The large LED makes it easy for the operator to check close at hand the telecommunication status and whether double tightening has occurred.
  • New Communication Mode permits use of the new R-CM Wireless Receiver with Interchangeable Modules. New Communication Mode extends wireless distance to around 20–30 meters, while also permitting R-CM monitoring of the transmitter battery voltage. This helps prevent transmission failures caused by unexpected reduction in voltage.
  • You can use the same receiver (R-CM) and the same setting controller (SB-FH2) for wireless CH settings as those for the FHM/FH wireless Pokayoke (error proofing) torque wrench. This gives you double tightening detection with the purchase of only the torque wrench, reducing purchase cost.
  • Traceability is connected. Torque wrenches can be identified with a 7-digit alphanumeric character ID or 3-digit ID, so the torque wrench used for tightening can be specified. This permits traceability. * The ID can be set using special software downloaded for free from “Software” at the bottom of this page.
  • Battery life: Can be used approx. 150,000 times. One AAA alkaline battery should provide enough power for more than 150,000 operations. For example, even if the number of times is 3,600 per day, the battery can be used for at least two months. This reduces battery expense and the number of battery replacements.
  • The model features interchangeable heads, permitting a wide variety of tightening tasks using different heads, including open end, ring head, and ratchet head.

Notes
  • As of April 2020, the CSPFHW torque wrench conforms to telecommunication standards in Japan (TELEC), the U.S. (FCC), Canada (IC), the EU (CE), Thailand (NTC), Taiwan (NCC), South Korea (KC), India (WPC), and Indonesia (SDPPI). It can also be used in China.

  • One R-CM receiver can communicate with a maximum of four torque devices, but it does not function with a mixture of new and old communication modes. (You can use the SB-FH2 setting controller to switch FHM and CSPFHW to the older communication mode).

 

Standard accessory
  • One AAA alkaline battery (for testing)

  • Protective cover FHW-PCV: 1

◆ How to order

When ordering, please specify the body type and the set torque value.

Example 1: Tohnichi CSPFHW50N3X15DXT Free

Example 2: Tohnichi CSPFHW100N3X15DXT70N・m

Example 3: Tohnichi CSPFHW25N3X10DXT Free + R-FHSET-AC

* R-FHSET-AC is a set composed of the wireless module for FHM/FH, the R-CM receiver, and the BA-8R (AC adaptor).

[Example 4] Tohnichi CSPFHW25N3X10DXT Free + R-FHSET-AC

* The R-FHSET is a set composed of the wireless module for FHM/FH, and the R-CM receiver.

◆ Things to remember when ordering
  • The CSPFHW torque wrench is pre-set, so torque settings require a tester.

 When ordering, please specify the torque values you intend to apply.

  • Can also be mounted on models other than the CSP. Please contact us for details.

  • The group channel and ID are initially set when you place the order. To change them, the SB-FH2 setting controller (sold separately) is required.
